question 302

Multiple Choice

Use the Quadratic Formula to solve for $y$ . $81 x ^ { 2 } - 90 x y + 25 y ^ { 2 } + 10 y = 0$

• A) \(y = \frac { 90 x - 10 \pm \sqrt { ( 90 x - 10 ) ^ { 2 } + 8100 x ^ { 2 } } } { 50 }\)
• B) \(y = \frac { 90 x + 10 \pm \sqrt { ( 90 x + 10 ) ^ { 2 } + 8100 x ^ { 2 } } } { 50 }\)
• C) \(y = \frac { 90 x + 10 \pm \sqrt { ( 90 x - 10 ) ^ { 2 } - 8100 x ^ { 2 } } } { 50 }\)
• D) \(y = \frac { 90 x - 10 \pm \sqrt { ( 90 x - 10 ) ^ { 2 } - 8100 x ^ { 2 } } } { 50 }\)
• E) \(y = \frac { 90 x - 10 \pm \sqrt { ( 90 x + 10 ) ^ { 2 } - 8100 x ^ { 2 } } } { 50 }\)
