Best ResponseYou've already chosen the best response.0Here a x c = 2 x 6 = 12 Now we have to break up 12 so that the two factors give product 12 and sum 4 Factors of 12 can be 1 x 12, 2 x 6, 3 x 4, Out of these, if we take the pair 2 x 6 and then modify it as 2 x 6, we get 2 x 6 = 12 and 2 + (6) = 4 So, we can say 2x^2 4x 6 = 2x^2 + 2x  6x  6 = 2x(x + 1) 6 (x + 1) Hence 2x^2 4x 6 = (2x  6) (x + 1)
