SOLUTION: how would you simplify {{{(3/(x+2))+(7/(x-4))}}} would the lcd be (x+2)(x-4) then you would get 3(x-4)+7(x+2) 3x+12+7x+14 10x+26 but im not sure

(3(x-4) + 7(x+2)) / ((x-4)(x-2)) =
:
(3x -12 + 7x +14) / ((x-4)(x-2)) =
:
(10x +2) / ((x-4)(x-2)) =
:
(2(5x + 1)) / ((x-4)(x-2))

Yes, that's the LCD, but 3(x - 4) IS NOT 3x + 12, and you forgot that the LCD should be included as this is not an EQUATION to be solved, but an EXPRESSION to be simplified.
