Clare Tucker · Answer 1

The difference of two numbers is 5 and the difference of their reciprocals is 1/10. find the no. s

Step-by-step explanation:

⇒ x (x-5) = 50

⇒ x2 - 5x - 50 = 0

⇒ x2 - 10x + 5x - 50 = 0

⇒ x (x - 10) + 5 (x - 10) = 0

⇒ (x+5) (x-10) = 0

⇒ (x+5) (x-10) = 0

⇒ x = - 5 or 10

⇒ x = 10 (x = - 5, rejected)
