A video on solving quadratic equations where the quadratic expression on one side has already been factorised and the other side of the equation is zero. This video also looks at the zero product property (also known as the null factor law).
00:00 Introduction and zero product property
01:19 Example 1 Solve (x+3)(x+8) = 0
03:35 Example 2 Solve (x-5)(x+2) = 0
04:30 Examples 3-4 Solve (x-1)(x-5) = 0 and x(x+7) = 0
05:46 Example 5 Solve (x+7)(x+7) = 0
