Answer + factor completely. x^2 - x - 30 = 2m^2 - 2m - 60 =

Looking at x^2 - x - 30, we see that 5*6=30, so we can immediately conclude that x^2 - x - 30 = (x+5)(x-6).  check this by multiplication.

2m^2 - 2m - 60 can be reduced to 2(m^2 - m - 30), which in turn can be factored as    2(m+5)(m-6).  The trick here is to notice how easily "2" can be factored out of the given equation.
