Answer 1

Answer:

Q. 10

Step-by-step explanation:

ans:- x = a + 1/a -----(1)

y = a - 1/a ------(2)

समीकरण (1) और (2) का वर्ग करके घटाने पर

x² - y² = (a + 1/a)² - (a - 1/a)²

x² - y² = a² + 1/a² + 2 - a² - 1/a² + 2

x² - y² = 4

दोनों पक्षों का वर्ग करने पर

(x² - y²)² = 16

(x²)² + (y²)² - 2x²y² = 16
