3m^2 -75

This is how I started to work it out.


  • algebra -

    Start by factoring out the GCF, which in this case is 3.
    So you get
    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)
