Hi,

6x^2+24x-72 = 6(x^2 + 4x - 12) = 4(x +6)(x-2)

                          F	First terms  x^2

                          O	Outside terms  -2x

                          I	Inside terms   +6x

                          L	Last terms   -12

Above is 'factoring'

If it were a questin of solving then 6x^2 + 24x - 72 = 0

In that case: 4(x+6)(x-2) = 0  and x = -6 OR x = 2
