anyone else love how satisfying it is the way he draws the parabolas? so smooth and perfect!

I was expecting him to explain how he got the -7 and 2 from the factor(x+7)(x-2). If I hadn’t watch other videos before this, I would have been guessing!

@@ChaosInFluff-vh7bh Because it's the roots/zero's/x-intercepts of the quadratic. The solution of a quadratic is the x-intercepts(x,0) which is when a line touches x while y is zero and a quadratic has two x-intercepts unless it doesn't go through the x-axis. When you factor out a quadratic into say (x+7) (x-2) you want to rewrite it as x+7=0, and x-2=0 because y or f(x) = 0 (when it comes to quadratic x-intercepts) and you want to solve for x when y is zero. Plus it doesn't change the equation which makes it easy to solve for x. To solve for x in algebra you need to say move the 7 to the other side of the =, and move the 2 to the other side of the =, but when you move numbers on different sides of the = you have to switch integers (such as +7 = -7 and -2 = +2) TLDR below: TLDR: Because to solve for the x-intercept of a quadratic, the brackets must equal 0 like: x+7=0 and x-2=0, then using algebra solve for x which usually is the opposite sign, x = -7 and x = +2 P.s I'm still practicing teaching things I learned as I'm still learning myself, so I hope I explained it well enough :)

You always have to change the signs to the opposite.

@@ChaosInFluff-vh7bh algebraically you set each factor equal to zero and solve for x, x+7=0, you subtract 7 on both sides to isolate which ends up giving X=-7, vice versa.
