    Hint:

    oblique asymptote y = (1/4)x + 1/2

    graph

    y=(1/4)x + 1/2 +(ax+b)/[(x+2)(x-1)]

    3 asymptotes , x = - 2 , x = 1 , y = ( x + 2 ) / 4 { line equation } ; zeros at x = - 3 & x = - 1  ; passes through ( 3 , 2)............so on the bottom (x + 2)(x - 1) are needed ; on the top are ( x + 3) (x + 1 ) ; top has to be one degree higher than the bottom so one of the factors has to have a power increased..so far : y = [ (x + 3) ( x + 1)² ] / [ ( x + 2 )(x - 1 ) meets the condition ;to go through 9 3 , 20 we need to multiply by 5/ 9.....y = [ 5 ( x + 3)(x+1)²] / [ 9 ( x + 2 )(x - 1) ]...but this does not have the line asymptote......will come back later
