Which of the following equations demonstrate that the set of polynomials is not closed
under the certain operations?
J
OA. Multiplication: (x²+2x) (x + 1) = x³ + 3x² + 2x
XO B. Multiplication: (32¹ +2³) (-22¹ +2³) = -62³ +27 +26
OC. Addition: (3¹ +2³) + (-22¹ +2³) = x² + 2x³
OD. Division: (22+2x) - (x + 1) = x + 1v
