WebSince this is a minus 3, the larger number needs the minus sign. So, you want: 2 (-5). Of course, you can also check this by just adding: 2 + (-5) = -3 (this works). While -2 + 5 = +3 (this doesn't work). Once you have selected the 2 numbers, use those numbers and their respective signs in your factors: (x+2) (x-5) Hope this helps. 1 comment
