Question

1. What is the sum of the polynomials?

Answer 1

I hope this helps you



1)


m+n+3+m+n+4


2m+2n+6


2)


10m-6-7m+4


3m-2


3)


4m-5-6m+7-2n


2-2m-2n

Answer 2

Answer:

1. 2m+2n+7

2. 3m-2

3.-2m+2-2n

Explanation:

To find the sum of given polynomials (m+n+3) +(m+n+4)

Firstly, open the parenthesis we will get  m+n+3+m+n+4  

After simplification we will get  2m+2n+7

To find the difference of given polynomials (10m-6)-(7m-4)

Firstly, open the parenthesis we will get 10m-6-7m+4

After simplification we will get  3m-2

Again to find the difference of the polynomials (4m-5)-(6m-7+2n)

Firstly, open the parenthesis we will get 4m-5-6m+7-2n

After simplification we will get -2m+2-2n
