Best ResponseYou've already chosen the best response.0Look at the first two terms, and take out a common factor. In this case, 3x. So the first two terms become 3x(x3). Now, the (x3) will always reappear in the part as well. What I mean is, it will be 3x(x3)___(x3). With a coefficent filling in the blank spot, and to figure out that coefficient just figure out what you need to multiply (x3) to get back to the latter two terms of the original which is 8x+24. So clearly, the coefficient in the blank is 8. So you have 3x(x3)8(x3), which factors into (x3)(3x8)
