About to start school, forgot how to do this:
8mn-10n+12m-15
8mn-10n+12m-15
-
factor by grouping...
8mn - 10n + 12m - 15
(8mn - 10n) + (12m - 15)
pull out the GCF of each pair
2n(4m - 5) + 3(4m - 5)
pull out the common (4m - 5) to give:
(4m - 5)(2n + 3)
ba-da-bing...
8mn - 10n + 12m - 15
(8mn - 10n) + (12m - 15)
pull out the GCF of each pair
2n(4m - 5) + 3(4m - 5)
pull out the common (4m - 5) to give:
(4m - 5)(2n + 3)
ba-da-bing...

There are no like terms, so that equation cannot be factored.
