crazy partial fraction integralintegral of (x)dx/((3x+7)^3) i have no idea how to solve for this integral , i'm learning integral by partial fraction and this is the hardest one that i can't do :( , if u know how to solve , please help me , thank you so much |

Re: crazy partial fraction integralDon't use partial fractions for this one, just set u = 3x+7, so du = 3 dx and x = (u-7)/3. |

Re: crazy partial fraction integralthank you so much, why didn't i think about using u substitution !!! :) |
