Solve. \( \sqrt{2 x+5}+9=0 \)

To solve the equation \( \sqrt{2x+5}+9=0 \), we first isolate the square root by subtracting 9 from both sides: \[ \sqrt{2x+5} = -9 \] However, the square root of any real number cannot be negative. Therefore, there are no real solutions to the equation. It's a reminder that sometimes equations can lead us to impossible scenarios! On a side note, if you ever encounter a similar equation, remember to check if the expression under the square root could potentially yield valid solutions in the real number system—just as we did here!
