question 92

Multiple Choice

Multiply, and then simplify if possible. Assume all variables represent positive real numbers.
- $( \sqrt { 35 } - \sqrt { 245 } ) ( \sqrt { 7 } + \sqrt { 5 } )$

• A) \(7 \sqrt { 5 } + 5 \sqrt { 7 } - 7 \sqrt { 35 } - 35\)
• B) \(7 \sqrt { 5 } - 5 \sqrt { 7 } + 7 \sqrt { 35 } + 35\)
• C) \(7 \sqrt { 5 } + 5 \sqrt { 7 } - 7 \sqrt { 35 } + 35\)
• D) \(7 \sqrt { 5 } + 5 \sqrt { 7 } + 7 \sqrt { 35 } + 35\)
