Rationalize the denominator of $\frac{\sqrt{5}+\sqrt{2}}{\sqrt{5}-\sqrt{2}}$. The answer can be written as $\frac{A+B\sqrt{C}}{D}$, where $A$, $B$, $C$, and $D$ are integers, $D$ is positive, and $C$ is not divisible by the square of any prime. If the greatest common divisor of $A$, $B$, and $D$ is 1, find $A+B+C+D$.

If you do not see the dollar signs in your question, that may be due to the browser you are using.

That is brilliant Hectictar! Thanks!

It is going int the sticky topics. Later I might combine it in one of the other threads but for now it can stand alone and people can be referred to it :)
