Question

( 3 m n 2 + 4 m 2 ) − ( 2 m 2 − 2 n + m n 2 )

Answer 1

3mn2+4m2-2m2+2n-mn2

2mn2+2m2+2n

2(mn2+m2+n)

Answer 2

To simplify the expression:

(3mn^2 + 4m^2) - (2m^2 - 2n + mn^2)

We can distribute the negative sign to the terms within the second parentheses:

= 3mn^2 + 4m^2 - 2m^2 + 2n - mn^2

Now, let's combine like terms:

= (3mn^2 - mn^2) + (4m^2 - 2m^2) + 2n

Simplifying further:

= 2mn^2 + 2m^2 + 2n

So, the simplified expression is 2mn^2 + 2m^2 + 2n.
