# The difference of

Let the required natural numbers x and (x + 5)

x < x + 5

Thus According to given condition, taking LCM  cross multiplying  Using the splitting middle term – the middle term of the general equation is divided in two such values that:

Product = a.c

For the given equation a = 1 b = 5 c = – 14

= 1. – 14 = – 14

And either of their sum or difference = b

= 5

Thus the two terms are 7 and – 2

Difference = 7 – 2 = 5

Product = 7. – 2 = – 14 x (x + 7) – 2(x + 7) = 0

(x – 2) (x + 7) = 0

(x – 2) = 0 or (x + 7) = 0

x = 2 or x = – 7

x = 2 (x < x + 3)

x + 5 = 2 + 5 = 7

Hence required natural numbers are 2 and 7.
