\(x = \)\({1\over2 + {1\over x + 2}}\)
This is what the equation looks like, now to simplify:
First you multiply the numerator and denominator by (x + 2):
It should look like: x = \({x + 2\over 2x + 4 + 1}\)
Then you multiply both sides of the equation by \(2x + 5\) to get \(2x^2 + 5x = x + 2\).
Now you subtract (x + 2) from both sides to end up with quadratic: \(2x^2 + 4x - 2 = 0\)
Next you use the quadratic formula x = \(-b {+\over} \sqrt{b^2 - 4ac}\over2a\) where a is the coefficient of x^2, b is the coefficient of x, and c is the constant. Plugging it in, we find that x = \(2\sqrt{2} - 2\), or x = \(-2\sqrt{2} - 2\)
