question 52

Multiple Choice

Solve the equation by extracting the square roots.
- $$( r + 3 ) ^ { 2 } = 15$$

• A) \(\mathrm { r } = \sqrt { 15 }\) or \(\mathrm { r } = \sqrt { 15 }\)
• B) \(r = - 3 + \sqrt { 15 }\) or \(r = - 3 - \sqrt { 15 }\)
• C) \(\mathrm { r } = \sqrt { 12 }\) or \(\mathrm { r } = - \sqrt { 12 }\)
• D) \(r = 3 + \sqrt { 15 }\) or \(r = 3 - \sqrt { 15 }\)
