Multiple Choice

Solve the equation using the quadratic formula.
- 4x2=−12x−64 x ^ { 2 } = - 12 x - 6


A) x=−3+32x = \frac { - 3 + \sqrt { 3 } } { 2 } or x=−3−32x = \frac { - 3 - \sqrt { 3 } } { 2 }
B) x=−12+32x = \frac { - 12 + \sqrt { 3 } } { 2 } or x=−12−32x = \frac { - 12 - \sqrt { 3 } } { 2 }
C) x=−3+152x = \frac { - 3 + \sqrt { 15 } } { 2 } or x=−3−152x = \frac { - 3 - \sqrt { 15 } } { 2 }
D) x=−3+38x = \frac { - 3 + \sqrt { 3 } } { 8 } or x=−3−38x = \frac { - 3 - \sqrt { 3 } } { 8 }
