        1 -16 83 -220
        
        x2 -16x +83 - 220/(x3-14x2+51x-54)
        
        (x3 - 14x2 + 51x - 54) ÷ (x + 2)
        
        Teacher made the mistake with the remainder where the true remainder is -220/(x+2)
        
        -2@ 1 -14 +51 -54

        Find P(3)
        
        3@ 1 0 0 -8 -1 0 2
        
        1 3 1 2 6 20
        
        P(3) = 20
        
        P(x) = x5 -8x3 -x2 +2
