im having a lot of trouble using the chain rule product rule and quotient rule..i can do them fine seperatly but when they're put together i cant get them like if you have (x^2-1)^4 (2-3x) i would start with(adsbygoogle = window.adsbygoogle || []).push({});

4(x^2-1)^3(2x)(2-3x)+(x^2-1)^4(-3)

have i done something wrong here because i never get the right answer with these ones i dont know if i messed up here or later on
