Question

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

Answer 1

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((-4)+4)=sqrt0=0`

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

`sqrt((-5)+4)=sqrt(-1)=i`

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