Question

If the sum of two natural numbers is 8
and their product is 15, find the numbers.
​

Answer 1

Answer:

5,3

Step-by-step explanation:

let's suppose the two numbers are X and Y

Now X + Y = 8. (given)

so X =8-Y

X × Y = 15 (given )

put X = 8-Y in that equation

So The numbers are 5 and 3

Answer 2

Step-by-step explanation:

Let x and y be the two number

x + y =8

x=8-y

And,

x×y=15

(8-y)y=15

y²-8y+15=0

y²-5y-3y+15=0

(y-5)(y-3)=0

y-5=0 and y-3=0

y=5 and y=3

Other number

x=8-5 =3 and x=8-3=5
