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

Solution for (3m^2+2n)-(m^2+2n)= equation:

Simplifying
(3m2 + 2n) + -1(m2 + 2n) = 0

Remove parenthesis around (3m2 + 2n)
3m2 + 2n + -1(m2 + 2n) = 0
3m2 + 2n + (m2 * -1 + 2n * -1) = 0
3m2 + 2n + (-1m2 + -2n) = 0

Reorder the terms:
3m2 + -1m2 + 2n + -2n = 0

Combine like terms: 3m2 + -1m2 = 2m2
2m2 + 2n + -2n = 0

Combine like terms: 2n + -2n = 0
2m2 + 0 = 0
2m2 = 0

Solving
2m2 = 0
