Question

What is the sum of the polynomials?

(m + n + 3) + (m + n + 4)?

Answer 1

2m+2n+7 is the answer to that

Answer 2

The sum of of the polynomials (m + n + 3) + (m + n + 4) is 2m + 2n +7

Explanation:

The given expression is (m + n + 3) + (m + n + 4)

we need to find the sum of this expression

so, first we add the similar terms

m + n + 3 + m + n + 4

first write the like term together and then constant,

⇒ m + m + n + n +3 + 4

⇒ 2m + 2n +3 + 4

⇒ 2m + 2n +7

Therefore, The sum of of the polynomials (m + n + 3) + (m + n + 4) is 2m + 2n +7
