Multiply, and Then Simplify If Possible $( \sqrt { 11 x } - 5 \sqrt { 2 } ) ( \sqrt { 11 x } - 5 \sqrt { 5 } )$

Multiple Choice

Multiply, and then simplify if possible. Assume all variables represent positive real numbers.
- $( \sqrt { 11 x } - 5 \sqrt { 2 } ) ( \sqrt { 11 x } - 5 \sqrt { 5 } )$

A) $121 x ^ { 2 } - 5 \sqrt { 55 x } - 5 \sqrt { 22 x } + 25 \sqrt { 10 }$
B) $11 x - 5 \sqrt { 110 x } + 25 \sqrt { 10 }$
C) $11 x - 5 \sqrt { 55 x } - 5 \sqrt { 22 x } + 25 \sqrt { 10 }$
D) $11 x - 5 \sqrt { 55 x } - 5 \sqrt { 22 x } + 25 \sqrt { 2 }$
