Posted by on .

Factor the following trinomial:
12x^2 - 11x + 2
Please help I have no idea how to do this!

  • Math - ,

    12x2 = 24
    look for two numbers which multiply to get 24 and have a sum of -11
    how about -3 and -8

    so 12x^2 - 11x + 2
    = 12x^2 - 3x - 8x + 2
    = 3x(4x - 1) - 2(4x - 1)
    = (4x-1)(3x-2)

  • Math - ,

    thanks
