Any positive number x has two square roots: one positive and one negative. For example, +3 and -3 are both square roots of 9.

Using a brilliant leap of imagination, mathematicians decided to call the first of these the positive root!

Why cant you evaluate the square root of negative twenty five using real numbers?

using basic math principles, you can't find the square root of a negative number because in order for a number to be a square root, you have to multiply it by itself to get your radical. since a negative times a negative and a positive times a positive are both positive, it is impossible to find the square root of a negative number
