# Area of a Region

Calculus Level pending

The region bounded by the curve $${\bf 2 x^2 + 12 xy - 3 y^2 - 42 = 0 }$$ and the parallel lines $${\bf -3\sqrt{13}\:x - 2\sqrt{13}\:y + 39 = 0 }$$ and $${\bf -3\sqrt{13}\:x - 2\sqrt{13}\:y - 39 = 0 }$$ can be expressed as $${\bf b\sqrt{a * b} (a\sqrt{\frac{b}{c}} + \sqrt{c}\:ln(\frac{a + \sqrt{b}}{\sqrt{c}})) }$$,  where $${\bf a\:,b\:,and\: c }$$ are coprime positive integers.



Find: $${\bf a + b + c. }$$
