A pоlynоmiаl P(x) аnd а divisоr d(x) are given. Use long division to find the quotient Q(x) and the remainder R(x) when P(x) is divided by d(x). Use the ^ symbol to write exponents if necessary. You MUST show your work for this question. On your scratch paper, copy the problem and show the steps you used to solve it. Type your answer below, then hold the paper up to your webcam for at least 5 seconds so that your work can be verified. Failure to do so could cause a score of 0 points for this question. P(x) = 16x3 + 24x2 - 15x - 4d(x) = 4x + 1 Q(x) = [q] R(x) = [r]
