1. The problem statement, all variables and given/known data
partial fractions

(-x^2+x+3)/((x-2)^2(x+1)) = A/(x-2) + B/((x-2)^2) + C/(x+1)

is my partial fractions set up right

A= -1/9 B = 1/3 C=1/9

Do you have a question, or....?

The setup looks right. I'm not so sure about your value for A though.

ok so the setup is right , i will go back through and solve for A again.
i think A=-10/9
