In a triangle, the sum of lengths of two sides is $\displaystyle x$ and the product of the lengths of the same two sides is $\displaystyle y$. If $\displaystyle x^2-c^2=y$, where $\displaystyle c$ is the length of the third side of the triangle, then the circumradius of the triangle is :
Official answer
(2)
$\displaystyle \frac{c}{\sqrt{3}}$
