Question

When it is best to solve using factoring and the Zero Product Property. Include at least one example of an equation that you would use this method to solve.

Answer 1

Explanation:

hello :

here is two examples:

1) x²-9=0 means : x²-3² = (x-3)(x+3) = 0 .... use identity : a²-b² = (a-b(a+b)

use the Zero Product Property; x-3=0 or x+3=0 so : x=3 or x= +3

2) x²+4x = 0....using factoring : x(x+4)=0 means : x=0 or x+4=0

x=0 or x= - 4
