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.
