solve 1-2/x=2/x+2. Express your answer in simplest radical form
Hello Bondra,
Use grouping symbols to clarify your post. I assume you mean this:
$\displaystyle 1-\frac{2}{x}=\frac{2}{x+2}$
$\displaystyle x(x+2)-2(x+2)=2x$
$\displaystyle x^2+2x-2x-4=2x$
$\displaystyle x^2-2x-4=0$
Use the quadratic formula to solve when in this form: $\displaystyle ax^2+bx+c=0$.
$\displaystyle x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$
Finish up!
