mn - 15 + 3m - 5n Rearranging: mn + 3m - 5n - 15 = m(n + 3) - 5(n + 3) = (m - 5)*(n + 3)
m(3m + 2)
jm + jn + km + kn = j(m + n) + k(m + n) = (m + n)(j + k)

510 cm or 5.10 m
mn - 4m - 5n + 20 = (mn - 5n) - (4m - 20) = n(m - 5) - 4(m - 5) = (m -5)(n - 4)
mn - 15 + 3m - 5n Rearranging: mn + 3m - 5n - 15 = m(n + 3) - 5(n + 3) = (m - 5)*(n + 3)
MN m and 5 are the terms. 5 is the costant
-mn(m - n2)(m + n2)
m = n/(n-1)
(m - 5)(n - 4)
(m - 5)(n - 4)
(m + 9)(m + 9)
12(m + 5)
The GCF is MN.
There is not the factor: there are two factors: (m - 1) and (1 - r)
factor it (m + 1)(9m + 2) m= -1 and -2/9
