question 44

Multiple Choice

Use the Quadratic Formula to solve for $y$ . $x ^ { 2 } - 12 x y - 10 y ^ { 2 } - 22 = 0$

• A) \(y = \frac { 12 x \pm \sqrt { 144 x ^ { 2 } + 40 \left( x ^ { 2 } + 22 \right) } } { - 20 }\)
• B) \(y = \frac { 12 x \pm \sqrt { 144 x ^ { 2 } + 40 \left( x ^ { 2 } - 22 \right) } } { - 20 }\)
• C) \(y = \frac { 12 x \pm \sqrt { 144 x ^ { 2 } + 40 \left( x ^ { 2 } - 22 \right) } } { 20 }\)
• D) \(y = \frac { 12 x \pm \sqrt { 144 x + 40 \left( x ^ { 2 } - 22 \right) } } { - 20 }\)
• E) \(y = \frac { 12 x \pm \sqrt { 144 x ^ { 2 } + 40 \left( x ^ { 2 } + 22 \right) } } { 20 }\)
