Use the Quadratic Formula to solve for yy .​ 81x290xy+25y2+10y=081 x ^ { 2 } - 90 x y + 25 y ^ { 2 } + 10 y = 0


A) y=90x10±(90x10) 2+8100x250y = \frac { 90 x - 10 \pm \sqrt { ( 90 x - 10 ) ^ { 2 } + 8100 x ^ { 2 } } } { 50 }
B) y=90x+10±(90x+10) 2+8100x250y = \frac { 90 x + 10 \pm \sqrt { ( 90 x + 10 ) ^ { 2 } + 8100 x ^ { 2 } } } { 50 }
C) y=90x+10±(90x10) 28100x250y = \frac { 90 x + 10 \pm \sqrt { ( 90 x - 10 ) ^ { 2 } - 8100 x ^ { 2 } } } { 50 }
D) y=90x10±(90x10) 28100x250y = \frac { 90 x - 10 \pm \sqrt { ( 90 x - 10 ) ^ { 2 } - 8100 x ^ { 2 } } } { 50 }
E) y=90x10±(90x+10) 28100x250y = \frac { 90 x - 10 \pm \sqrt { ( 90 x + 10 ) ^ { 2 } - 8100 x ^ { 2 } } } { 50 }
