**MathMate**, Tuesday, July 21, 2009 at 10:57pmStart by factoring out the GCF, which in this case is 3.

So you get

3m²-75

=3(m²-25)

The part in parentheses is the difference of two squares. Look up your course notes to see how to factor this part, namely using the standard form:

(A²-B²) = (A+B)(A-B)
