Explanation:

H+I=-5

HI=625

H=-b-5

I is a compounded number, so in other words there are no solutions for it.

There is no such real number!

a+b=-5

ab=625

a=-b-5

(-b-5)*b=625

-b^2-5b=625

b^2+5b+625=0

b=-5+-sqrt(25-2500)

This resulting in b as a complex number which means in the real numbers there is no such solutions!
