Q. ure you check for extraneous solutions.

\newline

3

.

\sqrt{2 x+5}=x+1

Square both sides: Square both sides to eliminate the square root. $\newline$ $(\sqrt{2x+5})^2 = (x+1)^2$ $\newline$ $2x + 5 = x^2 + 2x + 1$
Subtract to get equation: Subtract $2x$ from both sides to get the quadratic equation. $\newline$ $5 = x^2 + 1$
