How do I factor out/solve this quadratic problem?

{{{3x^2-15x-60}}}

First observe that you can factor out 3:

{{{3(x^2-5x-20)}}}

Can you think of two numbers which multiply to give -20
and which combine to give -5? No you can't, so there is
no way to factor further, so

{{{3(x^2-5x-20)}}}

is the final answer.  The comment that Scott made is wrong,
This is an expression, not an equation.  Expressions have no
solutions.
