Multiple Choice

Solve the equation by extracting the square roots.
- $$3 ( v + 1 ) ^ { 2 } = 80$$

• A) \(v = 1 - 4 \sqrt { \frac { 5 } { 2 } }\) or \(v = 1 + 4 \sqrt { \frac { 5 } { 2 } }\)
• B) \(v = - 1 - 4 \sqrt { \frac { 5 } { 2 } }\) or \(v = - 1 + 4 \sqrt { \frac { 5 } { 2 } }\)
• C) \(v = 1 - 4 \sqrt { 5 }\) or \(v = 1 + 4 \sqrt { 5 }\)
• D) \(v = - 1 - 4 \sqrt { \frac { 5 } { 3 } }\) or \(v = - 1 + 4 \sqrt { \frac { 5 } { 3 } }\)
