Zero Product Property

Definition

If   a × b = 0   then   a = 0   or   b = 0   or  a = b = 0

A product of factors is zero if and only if one or more of the factors is zero.

Examples

Solve x2 + x – 12 = 0

You can factor the left side as:

(x + 4)(x – 3) = 0

By the zero product property, either

x + 4 = 0 or x – 3 = 0

Which means

x = -4 or x = 3
