    Answer:

    1.  Reduce  3×2-6x-240   to    x^2 – 2x – 80

    2.  Use ” ^ ” to indicate exponentiation

    3.  Factor  x^2 – 2x – 80 using completing the

        x^2 – 2x + 1^2 – 1^2 – 80

            (x+1)^2 – 1  – 80

             (x+1)^2 – 81

             (x+1)^2 – 9^2  = (x+1-9)(x+1 +9), or (x-8)(x+10)

    Final answer, with all factors shown:      3(x-8)(x+10)
