Partial Fraction Decomposition help

[From: ] [author: ] [Date: 11-05-07] [Hit: ]
You dont indicate where A, B, and C are supposed to go, but those coefficients arent correct.(x² +2) / ((x-1)(x+2)²) = A/(x - 1) + B/(x + 2) + C/(x + 2)²,A = 1/3,......
(x^2 +2) / ((x-1)(x+2)^2)
I assume this has a repeated linear factor and I worked out an answer but I probably did it wrong anyway.
I got A=0.3125
B= -0.5
C= 0.33'

I don't know why you'd use decimal values. You don't indicate where A, B, and C are supposed to go, but those coefficients aren't correct. If you put

(x² +2) / ((x-1)(x+2)²) = A/(x - 1) + B/(x + 2) + C/(x + 2)²,

you should get

A = 1/3, B = 2/3, and C = -2.
