1. Resolve into partial (x 1) (x + 2)

fractions. x3

Sol: Now = (x 1) +(x 1)(x + 2)

3x 2(x 1)(x + 2)

3x 2 A BLet = +

(x 1)(x + 2) x 1 x + 2 3x 2 = A(x + 2) + B(x 1)

3x 2 = (A + B)x + (2A B) A + B = 3 ..... (1),

2A B = 2 ..... (2)1 8

By solving (1), (2) we get A = , B = 3 3

x3 A B= (x 1) + +

(x 1)(x + 2) x 1 x + 21 8

= (x 1) + +3(x 1) 3(x + 2)
