Lesson 54: Solving Quadratics (Zero-Product Property)

07/03/2016

Lesson on getting the values of the variables using the ZPP. ZPP is used when the expressions are made of factors, and in getting the values, equating the expression to 0 is necessary. Factoring can be used to draw out the factors of the expression.

0:18 3x(x+1)=0

0:47 x(2x-1)=0

1:13 (x+5)(3x+7)=0

2:05 5x^2 + 10x = 0

2:55 x^2 +7x + 12 = 0

3:55 h^2 + 10h = -21

4:54 5m^2 -45 = 0
