Solving Quadratic Equations by Factoring

  • Use factoring techniques to factor a quadratic expression. For trinomials, use the guess and check technique. Factor a greatest common factor first. Look for a perfect square trinomial and the difference of two squares.

  • Use the zero product property to set each factor equal to 0 and find the solutions.
