The square root of a number is any number that satisfies x in the equation x*x = y. In other words, 3 is the square root of 9 because 3 * 3 = 9. However, you might also notice that -3 would satisfy this rule as well. So square roots can be either positive or negative. A brief table of squares and their roots:
1 * 1 = 1
2 * 2 = 4
3 * 3 = 9
4 * 4 = 16
5 * 5 = 25
6 * 6 = 36
7 * 7 = 49
etc...
Remember that the negatives of these numbers are also square roots, as -2 * -2 = 4, and -5 * -5 = 25.

What is the square root of a negative number plus the square root of a negative number?
Nothing. You cannot have a square root of a negative number. The square root of negative one is called i, but i is an imaginary number. It does not exist and does not follow the properties of real numbers. (For example, if a and b are positive, then the square root of a times the square root of b is the square root of ab. But the square root of -7 is not the square root of 7 times i.)
How do you do a square root of a negative number that is not a perfect square?
The square root of a negative number is not real.
