Hello all,

Please I want to know the steps to find the integral primitive of this function:

I know the result :

The steps for normal function like

My problem is that I'm confused about (x

Also if we have x

Thank you for any help about this primitive.

Please I want to know the steps to find the integral primitive of this function:

**∫1/[(x**^{2})*(x+1)*(x-2)] dx.I know the result :

**1/4 ln(x) - 1/3 ln(x+1) + 1/12 ln(x-2) + 1/2x**The steps for normal function like

**1/[x*(x+1)*(x-2)]**were like : a/x + b/x+1 + c/x-2.My problem is that I'm confused about (x

^{2}), I see at the end like a derivative of x^{2}.Also if we have x

^{3}, I mean (**∫1/[(x**) we will have like a + b + c + d + e. ==>^{3})*(x+1)*(x-2)] dx.**-3/8 ln(x) +1/4x**^{2}+ 1/3 ln(x+1) + 1/24 ln(x-2) - 1/4xThank you for any help about this primitive.
