I'll give up after figuring out*Originally posted by rockinlationchess***i got a problem for every one let see how smart people are what two numbers do you add to give you 10 and multiply to give you 40***i*needs to appear in the solution.

x+y=10 and x*y=40*Originally posted by rockinlationchess***i got a problem for every one let see how smart people are what two numbers do you add to give you 10 and multiply to give you 40**

Rearranging the first:

y=10-x

Substituting into the second:

x*(10-x)=40

Simplifying and leaving zero on one side:

-1*x^2 + 10*x - 40 = 0

A quick check of b^2 - 4*a*c gives a negative answer meaning on real solutions to this quadratic (square root of a negative number).

x= 5 (+-) 3.8729*i

Therefore there are no real numbers which satisfy your criteria.
