Best ResponseYou've already chosen the best response.1You multiply the 3 and 28 together: 3*28 = 84 Now you find all factors of 84, such that adding both of them will give 20 So, 6 and 14 work because (6*14)= 84 and 6 + (14) = 20 So, what you do is write down 3x^2 6x 14x + 28 [because 6x14x = 20x, you break it down using the factors 06, 14 you found) Now, you factor the first 2 terms, and the last two terms: 3x(x2)  14(x2); now you have (x2) is a common factor, so you factor again: (x2)(3x14)
