I am having a hard time getting to factor this binomial: I have tried other methods but they do not seem to work... ah well. $4m^2-\frac{9}{25}.$
Thanks.

If you mean $4m^2-\frac{9}{25}$, note that the second term is $(\frac{3}{5})^2$ and you have a difference of squares.
I assume this is homework, so only ideas from me here.
Note that the formula is of the form $A^2-B^2$.
and we know that $A^2-B^2$ can be factored easily.
