Which two equations would be most appropriately solved by using the zero product property?

- (x-1) (x+9) = 0

4x^2 = 13

3x^2-6x=0

0.25x^2+0.8x-8=0

The answer is

- (x-1) (x+9) = 0

3x^2-6x=0

According to the zero product property:

If a * b = 0, then either a = 0 or b = 0

If - (x-1) (x+9) = 0, then either x - 1 = 0 or x + 9 = 0

3x^2-6x=0 need to be written in factor form:

x (3x - 6) = 0

So if x (3x - 6) = 0, ten either x = 0 or 3x - 6 = 0
