Question

the difference of two number is 3 and the difference of their square is 69.find the number

Answer 1

Heya user !!!

Here's the answer you are looking for

Let the numbers be x and y

The question says, their difference is 3

So, x - y = 3

x = 3 + y

Now we get the 2 numbers as y and (y+3)

Also, difference of their squares is 69

That is, x² - y² = 69

But x = y+3

So, (y+3)² - y² = 69

y² + 3² + 2(3)(y) - y² = 69

9 + 6y = 69

6y = 69 - 9 = 60

y = 60/6 = 10

x = y + 3 = 10 + 3 = 13

Therefore, the numbers are 10 and 13.
