Title: 4-5 Solving Quadratic Equations by Factoring


1
Unit 3
  • 4-5 Solving Quadratic Equations by Factoring

2
Solving Quadratics by Factoring
  • You can solve some quadratic equations in
    standard form by factoring the quadratic and
    using the Zero-product property

ZERO-PRODUCT PROPERTY If ab 0 , then a0 or b0
  • Steps to solve a quadratic by factoring
  • Factor ax2bxc0
  • Set each factor equal to zero (zero-product
    property)
  • Solve each equation
