    suppose x2 = a then your equation is -a-2x-4+2+2x=x+a

    I see, I thought they taught basic algebra in high school. Anyway, -1x2-2x-4+2+2x-1x+1x2 = -x^2 - 2x +4 +2 +2x -x +x^2. Now, you need to bunch up all the like terms together, so -x^2+x^2 -2x +2x -x -4 + 2 = -x -2 (because -x^2+x^2 = 0 and -2x+2x = 0 and -4 +2 = -2)

    yes, x = 1x. you don't need to write the '1' explicitly.
