Debrus:
this is all about circle theorems -- the one we need to solve this one is 'two different tangents drawn from an external point to the circle have equal length'
that said, do you have any idea of solving it?

Debrus:
...
2 tangents whose legths are the same:
\( 2x^2+3x-1=2x^2-4x+13 \)
\[ 2x^2+3x-1-13=2x^2-4x \]
\[ 2x^2+3x-14=2x^2-4x \]
\[ 2x^2-2x^2+3x-14=-4x \]
\[ 3x-14=-4x \]
\[ 3x+4x=14 \]
\[ 7x=14 \]
\[ x=\frac{14}{7} \]
\[ \LARGE X=? \]
