9.4: FACTORING TO SOLVE QUADRATIC EQUATIONS
2
ZERO-PRODUCT PROPERTY WITH EXAMPLES: Zero-Product Property: If ab = 0, then a = 0 or b = 0. ( If the quadratic is factored, then one of the factors must equal 0.)
3
STEPS TO SOLVE QUADRATIC EQUATIONS BY FACTORING: 1.Write polynomial in standard form 2.Factor 3.Set each factor equal to 0 4.Solve each equation for x
4
