Question 749833: (5m+5n)(6m-7n)
Answer by lenny460(1073)   (Show Source):
You can put this solution on YOUR website! (5m + 5n)(6m - 7n)
5m * 6m = 30m^2
5m * -7n = -35mn
5n * 6m = 30mn
5n * -7n = -35n^2
30m^2 - 35mn + 30mn - 35n^2
Combine like terms:
-35mn + 30mn = -5mn
30m^2 - 5mn - 35n^2
Answer:
30m^2 - 5mn - 35n^2
