Question

Which of the following equations demonstrate that the set of polynomials is
not closed under the certain operations?
IN
O A. Division: (x2-5x+3) =(x- 2) = x- 3+
X-2
B. Subtraction: 8x* + x*)-(-2x + x) = 5x
O C. Addition: (x2 + x) + (x + 1) = x2 + 2x+1
D. Multiplication: (x2 - 5x+3)(x-5)= x - 10x2 +28x - 15​

Answer 1

Answer:

A. Division: (x2-5x+3) =(x- 2) = x- 3+

X-2

Step-by-step explanation:

A. Division: (x2-5x+3) =(x- 2) = x- 3+  -3/X-2

This is not a polynomial since we have an x in the denominator
