12m + 9n - 4 - 10m + 6n = 2m + 15n - 4
factor by grouping 7m(m-2)+6n(2-m)

m^2 6n - 9n2 - 2m = (m - 3n)(m + 3n - 2)
(m - 3n)(m + 3n - 2)
11m + 6n - 2m + 9n = 9m + 15n or 3(3m + 5n)
12m + 9n - 4 - 10m + 6n = 2m + 15n - 4
-2m^4n(8m^3 - 6n^7 - 9)
7n3 + 6n = n*(7n2 + 6)
The GCF is 6.
factor by grouping 7m(m-2)+6n(2-m)
3(3n - 1)(n + 1)
6n2 + 16n can be factorised to give 2n(3n + 8) so the highest factor is 2n.
6n + 5n is 11n.
