1. The problem statement, all variables and given/known data 2n - 6m + 5n^2 - 15mn 2. Relevant equations No particular equation since this is factoring 3. The attempt at a solution Keep in mind that I struggle when it comes to grouping as I'm not sure where I'm supposed to start but.... 2n - 6m + 5n^2 - 15mn Group first 2 terms together 2n - 6m GCF is 2. Factor into... 2(n-3n) Group last 2 terms together 5n^2 - 15mn GCF is 5n. Factor into 5n(n - 3m) (For this part I'm not too sure what happens to the exponent. I assume me dividing 5n^2 by 5n turned it into a 1) Now I have 2(n+3)5n(n - 3m) From this point on I have no idea what to do. Help would be much appreciated.
