What two numbers add to make 11 but multiply to make 15?

Answer 1

The numbers are (11 -square root 61)/2 and (11+square root 61)/2

Answer 2

You can get this answer quickly in Wolfram Alpha, in this case with the input:a+b=11, ab=15

In this case, the answer is:

(11 + root(61))/2

and:

(11 - root(61))/2

Answer 3

They are 5.5 - sqrt(15.25) and 5.5 + sqrt(15.25).
