To simplify the expression \( 8\sqrt{11} - 10\sqrt{11} \), we can combine the like terms:
- Identify the like terms: Both terms are multiples of \( \sqrt{11} \).
- Combine them:
\[ 8\sqrt{11} - 10\sqrt{11} = (8 - 10)\sqrt{11} = -2\sqrt{11} \]
Therefore, the simplified expression is \( -2\sqrt{11} \).
From the provided options, the correct response is:
−2x√11.
