What two numbers add up to 20 and multiply to 40
I believe this isn't possible... I've considered all factors of 40, but none of them worked.
I agree, I could not find any answers for this.
Numbers don't have to be integers, they could be fractional, irrational, ... .
Go to www.desmos.com and in the graphing thing put both x+y-20 and xy=40.
