Question

Find two positive numbers whose product is 225 and whose sum is a minimum

Answer 1

-15^=225
-15+-15=-30

Answer 2

sooo what are the 2 numbers?

Answer 3

you cant have two numberwhose sum is negative and product is positive other than a square number ie, 4^2,5^2

only way is if you have -25(-1)(9)=225
-25+-1+9<0

Answer 4

Let S = x + y. Since xy = 225, y = 225/x.
Substitute into the sum to get
S = x + 225/x. Then
S' = 1 - 225/x^2, implying that 15/x = 1.
Then x = 15. The other number is also 15.
