Question

find the third proportional to:x/y+y/x and x/y​

Answer 1

Step-by-step explanation:

x - y)/(x + y).

Step-by-step explanation:

Let the third proportional to (x² - y²) and (x - y) be P.

Therefore, (x² - y²), (x - y) and P are in proportion.

=> (x² - y²) : (x - y) = (x - y) : P

=> (x² - y²)/(x - y) = (x - y)/P

=> P = (x - y)²/(x² - y²)

=> P = (x - y)(x - y)/(x + y)(x - y)

=> P = (x - y)/(x + y).

Therefore, the third proportional to (x² - y²) and (x - y) is (x - y)/(x +
