# How do you solve sqrt(x + 4) = -3?

There is no solution

#### Explanation:

We're dealing with a square root and equating it to a negative number - which is something we can't do.

For example, if $x = - 4$, then the square root is $\sqrt{\left(- 4\right) + 4} = \sqrt{0} = 0$

If, however, we change the value of $x$ to $x = - 5$, then

$\sqrt{\left(- 5\right) + 4} = \sqrt{- 1} = i$

and so there's no way to get a negative value from a square root.
