Factor the polynomial completely
3m^2 75
This is how I started to work it out.
(3m23)(m5)

Start by factoring out the GCF, which in this case is 3.
So you get
3m²75
=3(m²25)
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:
(A²B²) = (A+B)(AB)
