3.5 Solving Quadratic Equations by Factoring
Zero Product Property: If the product of several factors is equal to zero, then at least one of the
factors is equal to zero.
●
The only way to end up with zero when you multiply is if one of the numbers being
multiplied is zero.
If and are real numbers and
