I need help, when (3x^3 + px^2 + qx +8) is divided by (x^2 - 3x +2) , the remainder is (5x+6). how do we find the values of p and q? thank you :)

    the divisor x^2 -3x +2 is factorised to (x-2)(x-1) so you can find P(2) and P(1)

    so we have from what I did the following equations: 3p+q=-16 ; -2p-10=6 -2p=16 p=-8 now just plug this into our other equation to find q 3(-8)+q=-16 -24+q=-16
