Students will be able to use the Zero-Product Property.
Students will be able to factor polynomials using the GCF.

2. 1. Students will be able to use the Zero-Product Property.
Zero-Product Property – if the product of two real numbers is 0 (zero), then at least one of the numbers is 0 (zero).
If ab=0, then a and/or b have to be 0 (zero). or or
We say the roots, or solutions, or zeros are
and

What can we factor out of both terms?
Check using the Distributive Property!
Now solve using the zero-product property. or
