ok I'm having problems with these if anyone can help... integral of x^2(1+x^3)^(-1/3)dx and this other one integral between limits of 0 and 1 (6x+6)/(x^2+10x+6) This ends up in form alog3+blog2 I just need to know how to get there..

Just filling in a couple of steps... Find Let so Rearrange your original integral so that you have as a multiple, in this case by multiplying by a cleverly disguised 1, namely Now
