in 1–2 sentences, explain why the following operation is a closed system under subtraction. (9x2+17x+13)−(2x2+12x+11)

3 answers

The operation is a closed system under subtraction because both expressions being subtracted are polynomials, and the result of subtracting one polynomial from another will always yield another polynomial. This means that the set of polynomials is closed under the operation of subtraction.

can you break it down simpler

The operation is a closed system under subtraction because when you subtract one polynomial from another, you still get a polynomial. So, the result stays within the same type of mathematical object.
