Multiple Choice

Solve the system algebraically.
- x2+y2=123x−y=−2\begin{array} { l } x ^ { 2 } + y ^ { 2 } = 12 \\3 x - y = - 2\end{array}


A) (−3+295,1+3295) \left( \frac { - 3 + \sqrt { 29 } } { 5 } , \frac { 1 + 3 \sqrt { 29 } } { 5 } \right) and (−3−295,1−3295) \left( \frac { - 3 - \sqrt { 29 } } { 5 } , \frac { 1 - 3 \sqrt { 29 } } { 5 } \right)
B) {−3+2295,1+3295) \left\{ \frac { - 3 + 2 \sqrt { 29 } } { 5 } , \frac { 1 + 3 \sqrt { 29 } } { 5 } \right) and (−3−6295,1−6295) \left( \frac { - 3 - 6 \sqrt { 29 } } { 5 } , \frac { 1 - 6 \sqrt { 29 } } { 5 } \right)
C) {−3+295,−7+3295) \left\{ \frac { - 3 + \sqrt { 29 } } { 5 } , \frac { - 7 + 3 \sqrt { 29 } } { 5 } \right) and (−3−295,−7−3295) \left( \frac { - 3 - \sqrt { 29 } } { 5 } , \frac { - 7 - 3 \sqrt { 29 } } { 5 } \right)
D) (−3+295,1−3295) \left( \frac { - 3 + \sqrt { 29 } } { 5 } , \frac { 1 - 3 \sqrt { 29 } } { 5 } \right) and (−3−295,1+3295) \left( \frac { - 3 - \sqrt { 29 } } { 5 } , \frac { 1 + 3 \sqrt { 29 } } { 5 } \right)
