Factoring and Zero Product Property

What does it mean to "find the zeros" of a quadratic?

• Plug in 0 and solve the expression.

• Factor then set each factor equal to zero and solve to find x-intercepts

• Set the expression equal to zero and solve 

• Factor then set each factor equal to zero and solve to find y-intercepts
