Question

difference between two positive number is 2 and their product is 17 then their sum is

Answer 1

let two numbers be x and y
ATQ,

x-y=2
x=2+y ..........(1)

xy =17
(2+y)y=17
2y+y^2 -17=0 ......(2)

solve these equations by any method and find value of x and y.

Answer 2

Their sum is 8.48

Step-by-step explanation:

Let the two numbers be x and y

We are given that difference between two positive number is 2

So, x-y = 2---1

We are also given that their product is 17

So, xy = 17  ---2

Substitute the value of x from 2 in 1

$x-y = 2$

Plot 1 and 2 on graph

x-y = 2 -- Blue

xy = 17 -- Green

Intersection point will provide the solution

So, (x,y)=(5.24,3.24)

Their sum =5.24+3.24=8.48

Hence Their sum is 8.48
