This is the question: use long division to find the quotient Q(x) and the remainder R(x) when P(x) is divided by d(x) and express P(x) in the form d(x)*Q(x)+R(x) P(x) = x^3+4x^2-13x+60 d(x)=x+7 My answer was wrong:P(x)=(x+7)(x^2-3x+8)+6. somewhere in my divison, but I don't understand where. Help please!
