# Math Help - Finding quotient and remainder of polynomial with variable

1. ## Finding quotient and remainder of polynomial with variable

$
P(x)=3x^4-kx^3+7x^2-x+1
$

If $P(x)=Q(x) [x-3]+W$ determine $Q(x)$ and $W$

If $P(x)=Q(x) [x-3]+W$ determine $Q(x)$ and $W$
W = P(3) (why?).

To get Q(x), I suggest you do a polynomial long division. That is, divide x - 3 into P(X). This will also confirm the value of W.
