What are factor pairs?

Back

Factor pairs are two numbers that, when multiplied together, give a product. For example, the factor pairs of 12 are (1, 12), (2, 6), and (3, 4).

What is the significance of the zero product property in factoring?

Back

The zero product property states that if the product of two factors is zero, then at least one of the factors must be zero. This is used to solve quadratic equations.
