question 218

Multiple Choice

Solve the equation using the quadratic formula.
- $5 x ^ { 2 } + 12 x = - 2$

• A) \(x = \frac { - 6 + \sqrt { 26 } } { 10 }\) or \(x = \frac { - 6 - \sqrt { 26 } } { 10 }\)
• B) \(x = \frac { - 6 + \sqrt { 46 } } { 5 }\) or \(x = \frac { - 6 - \sqrt { 46 } } { 5 }\)
• C) \(x = \frac { - 6 + \sqrt { 26 } } { 5 }\) or \(x = \frac { - 6 - \sqrt { 26 } } { 5 }\)
• D) \(x = \frac { - 12 + \sqrt { 26 } } { 5 }\) or \(x = \frac { - 12 - \sqrt { 26 } } { 5 }\)
