Simplify the polynomial [(6x-8)-2x]-[(12x-7)-(4x-5)].

I came up with two answers:

36x^2 - 72x + 35 or

-12x^2 + 8x - 2

Are either one of these the correct answer?

    let's see...
    [(6x-8)-2x]-[(12x-7)-(4x-5)]
    [6x-8-2x]-[12x-7-4x+5]
    [4x-8]-[8x-2]
    4x-8-8x+2
    -8x-6

    Unless you have dropped some exponents or mistyped some operators ...
