3m*m=3m^2
-1*5=-5

Answer 4

ummm, ok you need to pick a number that multiply to get the last digit of the polynomial and add or subtract to get the middle digit. So we know that 3*5+(-1)=14 so then it is safe to say that we are going to use -1 and 5 to solve this problem. You can check your answer by foiling the problem back out
