Best ResponseYou've already chosen the best response.0Let (m+x) (n+y) = mn  15 + 3m  5n => mn+ym+xn+xy=mn15+3m5n

Best ResponseYou've already chosen the best response.0\[(a+b)(c+d) = a(c+d) + b(c+d) = ac + ad + bc + bd\] If you want to be clever, note that to get a +3m, you need to have a +3 multiply an m, and there's only one such equation.
