3x^4 + 15x^3y
All you have to do is multiply the variable out front by both parts of the inside

in these steps
1st : 3x^3 (x) = 3x^3+1 = 3x^4
2nd: 3x^3(5y) = 3(5) and x^3(y) = 15x^3y
combine
3x^4+15x^3y

3x^3(x+5y)=3x^ 3x+ 15y = x=1/15y perhaps???
參考: haven't done algebra in 20 years. haven't needed to...
