2x^2−7(x)−15 Rewrite −7 as −10 + 33Apply the distributive property.
2x^2 +(−10x+3x)−15Remove parentheses.2x^2− 10x + 3x −15 Group the first two terms and the last two terms.(2x^2 − 10x) + (3x−15)Factor out the greatest common factor (GCF) from each group.2x(x−5) + 3(x − 5)Factor the polynomial by factoring out the greatest common factor, x−5(x − 5) (2x + 3)
anwser is (x-5)(2x+3)
