Factoring ax2 + bx + c Lesson 10.5A Algebra 2 Factoring a Quadratic Trinomial Factor a Quadratic Expression To write a quadratic expression as the product of two linear expressions. Using the Discriminant A quadratic trinomial can be factored only if the discriminant is a perfect square. b b 2 4ac x 2a b2 – 4ac is the discriminant Using the Discriminant Determine whether the trinomial can be factored. x2 + 3x - 4 x2 + 3x - 6 Product-Sum Method To solve any quadratic equation of the form ax2 + bx + c = 0 we can use the Product-Sum Method. Product-Sum Method Factor x2 - 3x - 10 Product-Sum Method Factor x2 + 3x - 4 End of Lesson Factoring ax2 + bx + c Lesson 10.5B Algebra 2 Product-Sum Method Solve the equation x2 + 8x + 15 = 0 Product-Sum Method Solve the equation x2 + 4x = 12 End of Lesson
