Sometimes doing things like, "I am going to do this and this" confuses students because they have to think about two manipulations at once. He actually separated the square root on the right before taking the square root of the denominator. Excellent teacher.

why doesn't he have to say + or - the a when he takes square root of the a^2 at the end!? He said plus or minus for the big part that he takes square root of, but when he gets to square rooting the a^2 at the end, he doesn't do another + or - !

@@MathCuriousity + or - applies to the entire fraction. The 4a^2 there is a denominator and when you get the square root of it, it just stays as it is, just 2a. It's just normal addition and subtraction of fractions. The numerator is sqrt(b^2 - 4ac), the denominator of it is 2a. The numerator of the other fraction is -b, the denominator of it is 2a as well. They have the same denominator, and thus they can combine. Plus minus is two operations, addition and subtraction. If you're talking about plus-minus in the denominator, well here's the thing. If the denominator is negative and the numerator is positive, the whole fraction is negative. If the denominator is negative and the numerator is negative, the whole fraction is positive. If the denominator is positive and the numerator is positive, the whole fraction is positive. If the denominator is positive and the numerator is negative, the whole fraction is negative.

i know this is a few years late but ill share this anyway, that is actually a common misconception! the plus and minus only applies to: x^2 = 4 x = ± √4 x = ± 2 but in radicals, √(a^2) = |a| so √4 is always just 2 (called the principal root), even if √4 can be written as √ [(-2)^2], it is equal to |-2|, thus it's still just 2. It can only become -2 if it is indicated with a negative sign outside the radical, i.e. -√4. Hope this was helpful! xx

Say you had x^2-2x on the LHS. What you always have to do when you have something like this is to half the coefficient of x, then square it to get x^2-2x+((1/2)×(2))^2 = x^2-2x+1 = (x-1)^2. It's because the middle term is always twice the (square root of) other terms multiplied, e.g. x^2+6x+9 (9 =3^2) = (1)x^2+2(1x)(3)+3^2 (ax+b)^2 = a^2x^2+2abx+b^2

@carultch
Жыл бұрын
Because there isn't another b^2 in the second half of the term under the square root. There is no b^2 in the term -4*a*c. You cannot factor sqrt(x^2 - y) as x*sqrt(1 - y), so you cannot do the same with sqrt(b^2 - 4*a*c). In the special case that c=0, then the b^2 does do exactly what you are asking for. One might also think that a could equal zero for the same thing to happen, and they would be somewhat correct. But if a=0, then the entire denominator would equal zero, which cannot be. We'd also not even have a quadratic, as we'd have a line.

Yes! You are right. This is a quibble I have with all the derivations of the quadratic formula. They all ignore this point. At the end it doesn't matter +radical(b^2-4ac)/(-2a) = -radical(b^2-4ac)/2a. And -radical(b^2-4ac)/(-2a) = +radical(b^2-4ac)/(2a). So at the end we still get +-radical(b^2-4ac)/(2a). The order just gets changed, but we don't care about the order. But a way to clean this up is by to first multiply both sides by 4a^2 before taking square roots. 4a^2(x+b/(2a))^2 = b^2-4ac (2a(x+b/(2a))^2 = b^2-4ac Now we can take square root and avoid this issue: 2a(x+b/(2a)) = +-radical(b^2-4ac) etc... Now the issue of the sign of a doesn't matter.

Mainly Year 10, 11 and 12 on wootube, but also junior high school (Year 7 and 8). I'm guessing this is Year 10 content in Australia.
It's the third time I've been seen a video from Mr. Who about Quadratic formula derivation and I still pull out my hair when he straightforward takes the square root of the second member before even assuming b²-4ac is non negative... Actually the formula is correct if and and only if b²-4ac is non negative. And magically (luck or wellc chosen examples) all the examples he gives are Delta positive. This is really important to notice the case Delta < 0 because it might be tricky when students will face a non positive delta...

Eddie does talk about cases with delta < 0 later on, which is recorded on other videos. There is no need to talk about everything at once, it's better to teach stuff gradually. Besides, the formula is always correct, even if the discriminant is negative, you just have to look outside of real numbers.

@@vooyeq1730 No it is not, as the formula in this case would be +/_( i sqrt(|b^2 - 4ac|) /2a. This is not semblable One has to be rigorous about it

But a is not equal to zero

If a were equal to zero, you wouldn't even have a quadratic equation in the first place; you'd have a linear equation, and you wouldn't need to even think about this formula.

Good news!!!!!!!!! Therefore repent and turn back, so that your sins may be wiped out, that seasons of refreshing may come from the presence of the Lord, and that he may send Jesus, who has been appointed for you as the Messiah. Acts 3:19?-?20 CSB From then on Jesus began to preach, “Repent, because the kingdom of heaven has come near.” Matthew 4:17 CSB “The time is fulfilled, and the kingdom of God has come near. Repent and believe the good news!” Mark 1:15 CSB Jesus replied, “Truly I tell you, unless someone is born again, he cannot see the kingdom of God.” Jesus answered, “Truly I tell you, unless someone is born of water and the Spirit, he cannot enter the kingdom of God. John 3:3?, ?5 CSB Whoever claims to live in him must live as Jesus did. 1 John 2:6 NIV 1john.bible/1-john-2-6 Jesus told him, “I am the way, the truth, and the life. No one comes to the Father except through me. John 14:6 CSB For God loved the world so much that he gave his only Son, so that everyone who believes in him may not die but have eternal life. John 3:16 GNB bible.com/bible/296/jhn.3.16.GNB _Jesus_ actually died, *_GOD_* has _His blood_ as a sacrifice for your sins. *_GOD_* killed *_His_*_ Only Son_ for you. All your sins: sexual immorality (fornication, adultery(lust), homosexual sex, pornography) murder( hating someone, envying, abortion and killing someone) , theft( murder, lying, abuse, corruption, disrespect, racism) and idolatry (greed, love of money, worship of other gods and pride) can be forgiven only if you believe in _Jesus_; that __*_God_* sacrificed _Him_ for the atonement of all your sins, and that_*He*_ raised _Him_ up 3 days later. And now He sits on the Right Hand of *_The Father_*__, ruling over all creation as __*_Lord and Saviour_* of the world. Jesus Christ died for your sins, and only through Him you can be forgiven of all your sins. You only go to heaven because of faith and belief in The death and resurrection of _The Son of _*_God_* for the sins of the world. Hell is for those reject GOD'S Only Son, they will be burnt by the wrath of The Almighty God. Believe that all your sins are forgiven because of The Blood of Jesus, who is The Messiah, The Saviour. Repent, turn away from your sins and live because, *_Jesus Lives_*

I think the coefficient a can't be any number, because if it were a zero, you would have a linear equation and not a quadratic.

Well, I get what you mean, but this is a formula for quadratic equations, and if a is equal to zero, you have a linear equation instead.

You made a mistake when you were substituting the numbers into your formula where -b isnt 1 its -1 because its -(b) or -(1)

If you look closely, there's already a - before the b so it's technically -(-1) = 1 so he was correct

Never fully got this in 1992. Now I finally understand it🥹 And yes, better math teachers slow down and explain each step because it’s a lot of steps. Perfect!
