So, the + / - means there are two answers, one that adds the √ (-24) and one that subtracts the √ (-24). You can leave that the way it is as + / -
The negative inside the square root is an imaginary number "i" = √ (-1)
This is whats called a complex number which has the imaginary number "i".
Factor out the imaginary number and any perfect square factors of 24.
24 = 6 * 4
4 is a perfect square of 2, so 2 factors out of the square root.
-1 + / - √ (-24)
-1 + / - i√ (6*2²)
-1 + / - 2i√ (6)

First find the square root of - 24 which would be - 4.898979486 then either subtract 1 or add negative 1, it's the same thing, and that would give you - 5.898979486.
