If the question is, "What is the solution to 2n2 + 6n - 108 = 0 ?"The equation can be factored : 2n2 + 6n - 108 = (2n - 12)(n + 9) = 0If 2n -12 = 0 then n = 6If n + 9 = 0 then n = -9The roots of this equation are n = 6 and n = -9.
factor by grouping 7m(m-2)+6n(2-m)
(m - 3n)(m + 3n - 2)
(m - 3n)(m + 3n - 2)
3(3n - 1)(n + 1)

7n3 + 6n = n*(7n2 + 6)
The GCF is 6.

(m - 3n)(m + 3n - 2)
(m - 3n)(m + 3n - 2)
3(3n - 1)(n + 1)
6n + 5n is 11n.
6n2 + 16n can be factorised to give 2n(3n + 8) so the highest factor is 2n.
n^2(n + 6)(n^2 - 6n + 36)
5mn + 6n - 14
6n = 12 n = 2
