For a polynomial of the form a x 2 + b x + c a x 2 + b x + c , rewrite the middle term as a sum of two terms whose product is a ⋅ c = 24 ⋅ − 5 = − 120 a ⋅ c = 24 ⋅ - 5 = - 120 and whose sum is b = 14 b = 14 . Tap for more steps... 24 x 2 − 6 x + 20 x − 5 24 x 2 - 6 x + 20 x - 5 Factor out the greatest common factor from each group. Tap for more steps... 6 x ( 4 x − 1 ) + 5 ( 4 x − 1 ) 6 x ( 4 x - 1 ) + 5 ( 4 x - 1 ) Factor the polynomial by factoring out the greatest common factor, 4 x − 1 4 x - 1 . ( 4 x − 1 ) ( 6 x + 5 )
