If you square both sides you getWhat's the answer to the problem sqrt(5x+3)=-2, solving for x?

If you square both sides, you get 2=-2, which is wrong. Does it have to

do with complex/imaginary numbers? Or does it have no answer at all?

$$5x+3=4$$

And following that gives

$$5x=1$$

$$x=\frac{1}{5}$$

However, when putting in the value of x into your original equation, we want to take only the positive root, so your equation has no solutions.
