What multiplies to 3 and adds to 2

There is no pair of real numbers that can do that job.

The two numbers that CAN are ...

1 + √2 i

and

1 - √2 i

The ' i ' is the symbol used to stand for the square root of - 1.

(Yes, I know ... Negative numbers don't have square roots.

But there's a whole section of math built on the idea of the

square root of - 1, and the symbol most often used to represent

that is ' i ' ... for "imaginary".)
