The question you have asked is very vague, there are an infinite pairs of numbers that give -220 when they are multiplied by each other.

For example -11 and 20, -20 and 11, etc.

If you would like to know if there are two equal numbers that can be multiplied to give -220, there are none in the real number system. The complex number `i*2*sqrt 55` when multiplied with itself gives -220.
