2x2 − x − 15 2 x 2 - x - 15 For a polynomial of the form ax2 +bx+ c a x 2 + b x + c, rewrite the middle term as a sum of two terms whose product is a⋅c = 2⋅−15 = −30 a ⋅ c = 2 ⋅ - 15 = - 30 and
Given the function f (x) = 2x^2 -x -15 We need to solve for x by factoring. First we have a quadratic equation. Then we can simplify into two factor. ==> f (x) = 2x^2 -x -15 We will
