## Homework Statement

How many real solutions does the equation √x+5=x have?

## Homework Equations

n/a

## The Attempt at a Solution

I squared both sides so I got x+5=x^2 then I formed a quadratic equation: x^2-x-5=0

I got two real solutions but the answer is one.

I know it has something to do with x+5 being sqrooted but I don't know how to go about solving it.
