Please help I really don't know how to find decomposition. 
write the partial fraction decomposition of the given rational expression.
    x^2/ (x-2)^2(x+1)

anonymous · Answer

is it yours? $$\frac{ x^2 }{ (x-2)^2(x+1) }$$

anonymous · Answer

take a look at http://www.purplemath.com/modules/partfrac2.htm everything there, just imitate

yes

anonymous · Answer

look at page 2 at the link I give, if you still not understand, let me know then

anonymous · Answer

alright thanks for the link!

I just want to double check if this is the right answer

$$\frac{ \frac{ 1 }{ 9 } }{ (x+1) }+\frac{ \frac{ 13 }{ 18 } }{ (x-2) }+\frac{ 1 }{ (x-2)^{2} }$$
