So, this problem doesn't have any "действительные" answers - it has only complex answers.
Cool, Math Hunter! :)

In fact, sqrt(-1) has 2 roots: -i and +i.

[@mathshunter]

Square root is a function and any function can not have more than 1 values. So sqrt(-1) = i

[@ALEX.1R]

​​@@mathshunterwik Imaginary uniti: There are two complex square roots of −1: i and −i, just as there are two complex square roots of every real number other than zero (which has one double square root).

The problem appears to have been wrongly structured from two angles. One, one of the variables has to be a negative number. Two, product is not exactly 100.
Accordingly,
X = 16.1803399 and Y = - 6.1803399
Verification
X + Y = 10
16.1803399 + (-6.1803399) = 10
XY = 16.1803399 x (-6.1803399) = - 100. 0000001
Please correct me if I am wrong.
