Multiple Choice

Use the Quadratic Formula to solve for $y$ .​ $5 x ^ { 2 } + 10 x y + 11 y ^ { 2 } + 9 x - 10 y - 42 = 0$ ​

• A) \(y = \frac { - ( 10 x - 10 ) \pm \sqrt { ( 10 x - 10 ) ^ { 2 } - 44 \left( 5 x ^ { 2 } - 9 x - 42 \right) } } { 22 }\)
• B) \(y = \frac { ( 10 x - 10 ) \pm \sqrt { ( 10 x - 10 ) ^ { 2 } - 44 \left( 5 x ^ { 2 } + 9 x - 42 \right) } } { 22 }\)
• C) \(y = \frac { - ( 10 x - 10 ) \pm \sqrt { ( 10 x - 10 ) ^ { 2 } - 44 \left( 5 x ^ { 2 } + 9 x - 42 \right) } } { 22 }\)
• D) \(y = \frac { - ( 10 x - 10 ) \pm \sqrt { ( 10 x - 10 ) ^ { 2 } - 44 \left( 5 x ^ { 2 } + 9 x - 42 \right) } } { 22 }\)
• E) \(y = \frac { - ( 10 x - 10 ) \pm \sqrt { ( 10 x - 10 ) ^ { 2 } + 44 \left( 5 x ^ { 2 } + 9 x - 42 \right) } } { 22 }\)
