To solve this expression, we need to simplify it step by step. Here's the process:
Combine like terms:
Combine the constant terms: 2 - 9 = -7
Combine the terms with "s": -2.5s - 3s = -5.5s
Reorganize the expression:
Rearrange the terms to group the square root separately: -5.5s + 5 + 9√s
Factor out the square root:
Notice that all terms have a common factor of √s: √s(-5.5√s + 5 + 9)
Simplify:
The expression is now simplified to √s(-5.5√s + 5 + 9).
Therefore, the simplified expression is √s(-5.5√s + 5 + 9).
