fedepess Posted September 15, 2013 Report Share Posted September 15, 2013 hey guys, it's 2 hours that I'm trying to solve this excercise but I'm not able to do it in any way. Our teacher hasn't yeat explained us how to do it, but I don't want to wait for lesson, I just want to do it now so the topic is binomial expansion, in this case products of binomial expansion.(3x + 7)(x^2 - 2x)^4 I tried using pascal and other things with the techniques that I've learnt, but this one just wont come. Please help me Reply Link to post Share on other sites More sharing options...
