    When we have a quadratic, , we can factor by finding what two numbers when multiplied equal a*c and when added equal b.

    In this case, find what two numbers when multiplied equal 60 and when added equal 19.

    How about 15 and 4? 15*4=60 and 15+4=19.



    Now, group, factor out a common term, and finish.

    Remember, what is inside the parentheses must be the same for it to work.
