First: when there's four terms > group "like" terms in parenthesis:

(m^2 - 2m) - (9n^2 + 6n)

Sec: factor both sets of parenthesis (find the least common factor from each set and multiply it by the remaining terms to get the inside expression) >

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

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

*Both sets of parenthesis have "2" and one is negative, the negative sign is used for the final answer.

should be (a)

Rearrange to
m^2-9n^2-2m+6n

Then
(m^2-(3n)^2)-2(m-3n)

think u should able to solve the rest
