Question

Which expression can be used to find the difference of the polynomials? (4m – 5) – (6m – 7 + 2n)

Answer 1

D

Explanation:

(4m – 5) + (–6m + 7 – 2n)

Answer 2

The difference of the given polynomial is -2m-2n+2

Explanation:

The difference of the polynomial is greater number minus smaller number

we have expression (4m-5)-(6m-7+2n)

After opening the parenthesis we will get 4m-5-6m+7-2n

Now, solving like terms with each other means simplifying terms of "n" with "n" and "m" with "m"we will get -2m+2-2n

Therefore, the difference of the given polynomial is -2m-2n+2
