    \[4x-4 \over x-2 \]\[= x+6 \over x+5 \] +2

    it's supposed to be a fraction but for some reason it didn't work.

    a fraction over a fraction right?

    it's 4x-4 over x-2 = x+6 over x+5 (not in fraction form is the +2)

    idk why it came up over each other like that. I have the problem presented in a straight line.

    \[\frac{4x-4}{x-2} = \frac{x+6}{x+5} ??\]

    ok..... the key is to get common denominators straight across.

    (4x-4)(x+5) = (x+6)(x-2) + 2(x+5)(x-2)

    the common denom fades away to that :)

    4xx +16x -20 = xx +4x -12 + 2xx +6x -20

    4xx - xx - 2xx = x^2 16x -4x -6x = +6x -20 +12 +20 = +12 x^2 +6x +12 = 0

    -6/2 +- sqrt(36 -4(12))/2 looks to be imaginary solutions; or i messed up calculting :)

    just to make sure I enter it correctly into the online assignment, does it look like this. only i type the same thing twice, one + one 0\[-6 \over 2 +\sqrt{36-4(12)}\] over 2

    it wont let me type in the square root of 12 negative.. should that become positive?

    the answer can be simplified; how it wants you to input it into the program is probably in simplest form; doe sit want "real" roots? or any roots?

    both isnt an option :) the 2 spots are most likely for the +sqrt and the -sqrt.
