The general solution would be any pair of numbers (A, B) where A is a complex number composed of a real number plus the square root of a real number, and b is the same complex number minus the square root of the same number, so long as the square root is an irrational number. Note that A does not need to be an integer, it can be a fraction.
The simplest would be where the real number is zero: sqrt(2) + -squrt(2) = 0, and sqrt(2) * -sqrt(2) = 2.
You can't use numbers like sqrt(4) because they are not irrational numbers.
You can use odd things like (19.5 + squrt(2)) and (19.5 - sqrt(2)), as you get a ratiional number (a fraction) from the sum and from the product.
