Multiple Choice

Solve the equation for the indicated variable. Assume no denominator is 0.
- $$2 x ^ { 2 } - 4 x y + 3 y ^ { 2 } = 1 , \text { for } x$$

A) $x = \frac { 2 y \pm \sqrt { 2 - 2 y ^ { 2 } } } { 2 }$

B) $x = y \pm ( 1 - y )$

C) $x = - y \pm \sqrt { 1 - y ^ { 2 } }$

D) $x = - y \pm 2 \sqrt { 1 - y ^ { 2 } }$
