# Find $C$

Algebra Level 5

$\large A(\sqrt{3}-\sqrt{2})x^2+\frac{B}{\sqrt{3}+\sqrt{2}}x+C=0$

If $E$ and $F$ are real roots of the quadratic equation above, where $A= \sqrt [4] {49+20\sqrt{6}}$ and $B=8\sqrt{3}+\dfrac{8\sqrt{6}}{\sqrt{3}}+\dfrac{16}{\sqrt{3}} + \cdots$ and that $\left|E-F\right|=(6\sqrt{6})^k$, where $k=\log _6 \left(10\right)-2\log _6\left(\sqrt{5}\right)+\log _6\sqrt{\log _6\left(18\right)+\log _6\left(72\right)}$, find the value of $C$.
