Simplify the following expression

2(3 x - 2)(2nd Power) - 3x (x + 1) + 4

  • algebra -

    expand the first term and the second term

    2(9x^2-12x+4)-3x^2-3x + 4
    18x^2-24x+8-3x^2-3x+4
    gather terms
    15x^2-27x+12
    (3x-3)(5x-4)
    check that.

  • algebra -

    2 (3 x - 2)^2 - 3 x^2 -3 x + 4

    2 (9x^2 - 12 x +4) - 3 x^2 -3x + 4

    18 x^2 - 24 x + 8 - 3x^2 -3x + 4

    15 x^2 -27 x + 12
    or
    3(5 x^2 - 9 x + 4)

  • algebra -

    Oh, you can factor more
    3(5 x^2 - 9 x + 4)
    3 (5x-4)(x-1)
