Question

add:. 3m²n+5mn²-7mn and 2m²n-mn²+mn
​

Answer 1

Given:

$3m^{2} n+5mn^{2} -7mn$

and, $2xm^{2} n-mn^{2} +mn$

To find:

The sum of $3m^{2} n+5mn^{2} -7mn$

and, $2xm^{2} n-mn^{2} +mn$

Step-by-step explanation:

• We need to find the sum of the two equations given. That means we need to add both equations in order to get the solution.

Solution:

$= 3m^{2} n+5mn^{2} -7mn+ 2m^{2} n- mn^{2} +mn\\\\= 5m^{2}n +4mn^{2} -6mn$

Hence, after adding the two equations we will get

$= 5m^{2}n +4mn^{2} -6mn$
