We have 2 terms:
and

<h2>So what's the problem?</h2>The function (square root of x) only returns positive values!
(See the attached image for a graph of )
Since neither of the terms can be negative, it can't be equal to -3. In other words, no matter what we put as , we can't solve the solution, so we say that the equation <em>does not have any solutions.</em>
