    Simplify the left hand side will give you (4x)/(x^2 - 4) = 1 [(4x)/(x^2 - 4) ]- 1 = 0 (x^2 - 4x - 4)/(x^2 - 4) = 0 => x^2 -4x -4 = 0 which you can solve by using the quadratic formula

    roots are \[-2 (\sqrt(2) -1)and 2 ( \sqrt(2) +1)\]

    \[ x=\frac{-b \pm \sqrt {b^2-4ac}}{2a}, \] which a is the coefficient of the x^2 term b is the coefficient of the x^1 term c is the coefficient of the x^0 term

    Find the common denominator which is (x-2)(x+2) then the equation is \[x^2 -4x -4 = 0\]

    \[ x=\frac{4 \pm \sqrt {4^2+4(4)}}{2}, \]
