Question

if the sum of two natural numbers is 8 and their product is 15 find the number

Answer 1

hey mate here is your


______

well, there are many multiplication and sum

so let us write them

the product is 15
so two natural number can be✔

$1 \times 15 \\ 3 \times 5$
now the sum is 8

now two numbers can be

✔
$1 + 7 \\ 6 + 2 \\ 3 + 5 \\ there \: are \: more \: but \: let \: us \: stop \: because \: we \: find \: the \: answer$
so the two natural number is 3,5

to clarify it
let us do calculation

⭐for the sum result should be 8

$3 + 5 = 8$
⭐ product should be 15

$3 \times 5 = 15$
therefore the answer is 3,5

Answer 2

Here is your answer

Let the number are x and y

ATQ. x + y = 8 and XY = 15

x = 8-y. Put it in XY = 15 We get

$(8 - y)y = 15 \\ 8y - y {}^{2} = 15 \\ - y {}^{2} + 8y - 15 = 0 \\ y {}^{2} - 8y + 15 = 0 \\ y {}^{2} - 5y - 3y + 15 = 0 \\ y(y - 5) - 3(y - 5) = 0 \\ (y - 5)(y - 3) = 0 \\ y = 3 \\ y = 5$
X = 8 -3 =5
X = 8 - 5. =3

so the number are 3 and 5 Answer

Hope it helps you
