Solve. LaTeX:  \displaystyle \sqrt{x + 24}=\sqrt{x - 6} + 1

Squaring both sides gives LaTeX:  \displaystyle x + 24=x + 2 \sqrt{x - 6} - 5 . Isolating the radical gives LaTeX:  \displaystyle \frac{29}{2}=\sqrt{x - 6} Squaring again gives LaTeX:  \displaystyle \frac{841}{4}=x - 6 . Solving for LaTeX:  \displaystyle x gives LaTeX:  \displaystyle x=\frac{865}{4} . Checking the solution, LaTeX:  \displaystyle x = \frac{865}{4} , in the original equation gives LaTeX:  \displaystyle \frac{31}{2} = \frac{31}{2} which is true so the solution checks.
