If the sum of 2 numbers is 4.5 and their product is 5 what is the 2 numbers?

Answer 1

Let x = one number = 2 or 2.5

Let y = the other number = 2.5 or 2

(x)(y)=5

x+y=4.5

y=4.5-x

(x)(y)=5

(x)(4.5-x)=5

4.5x-x^2-5=0

I used the quadratic formula to get x.

x=2 or x=2.5

(x)(y)=5

(2)(y)=5

y=5/2

y=2.5

(x)(y)=5

(2.5)(y)=5

y=5/2.5

y=2
