2 Points Which of the following equations demonstrate that the set of polynomials is
not closed under the certain operations?
O A. Multiplication: (3x4 + x)(-2x4 + x) = -6x8 + x? + x®
X
O B. Division: (x2 + 2x) = (x + 1) = x +
X + 1
C. Multiplication: (x2 + 2x)(x + 1) = x+3x2+2x
O D. Addition: (3 x4 + x°) + (-2x4 + x) = x4 + 2x2
