I need help with methods of factoring. Trial and error? Here's an example of the problems. 3x^3+15x^2+18x.

OpenStudy (turingtest):

yes, do trial and error with numbers like \[\pm0\pm1\pm3\]

I don't understand what trial and error even is. I just graduated high school and I was never taught this. Lol. Can someone show me how to do this problem? :(

OpenStudy (turingtest):

plug in x=0 dos that make the whole thing 0 ?
