    what is the degree if you multiply x^2*(x+2) ?

    not quite... \[\large x^2(x+2)=x^3+2x \]... agreed?

    so that's a third degree polynomial.. and what is the remainder if we take \(\large x^3+2x \) divided by \(\large x+2 \) ???

    remember we just multiplied it out to get that third degree polynomial...

    that's what i was asking in when we were working with the polynomial x^3 + 2x... the remainder when \(\large x^3+2x \) divided by \(\large x+2 \) is zero....
