Question

Simplify the polynomial(-8×)+×+(-2×)​

Answer 1

-9x

Explanation:

Without the confusing parentheses, this "polynomial" becomes -8x + x -2x. If we take 2 away from -8, it becomes -10. If we add a positive x, it becomes -9x. Therefore, the answer is (the monomial) -9x.

Answer 2

The correct answer is -9x

Explanation:

It is given a polynomial,

p(x) = (-8x) + x + (-2x)​

To simplify p(x)

p(x) = (-8x) + x + (-2x)​

= -8x + x - 2x

= -8x - 2x + x

= -10x + x

= -9x

(-8x) + x + (-2x)​ = -9x

Therefore the correct answer is -9x
