Answer:

$\sqrt{x^2+y^2}-x$

Step-by-step explanation:

$\textsf{Mulitply by}\quad\dfrac{\sqrt{x^2+y^2}-x}{\sqrt{x^2+y^2}-x}:$

$\implies \dfrac{y^2}{\sqrt{x^2+y^2}+x} \times \dfrac{\sqrt{x^2+y^2}-x}{\sqrt{x^2+y^2}-x}$

$\implies \dfrac{y^2(\sqrt{x^2+y^2}-x)}{(\sqrt{x^2+y^2}+x)(\sqrt{x^2+y^2}-x)}$

$\implies \dfrac{y^2(\sqrt{x^2+y^2}-x)}{(\sqrt{x^2+y^2})^2-x^2}$

$\implies \dfrac{y^2(\sqrt{x^2+y^2}-x)}{x^2+y^2-x^2}$

$\implies \dfrac{y^2(\sqrt{x^2+y^2}-x)}{y^2}$

$\textsf{Cancel the common factor}\:y^2:$

$\implies \sqrt{x^2+y^2}-x$
