Question

x-1/x= 1/2 find the value of 4x²+4/x²

Answer 1

Heya!!

x - 1/x = (1/2)

Squaring on both sides we have!!)

(x -1/x)² = (1/2)²

x² + 1/x² - 2 = (1/4)

x² + 1/x² = (1/4) + 2

x² + 1/x² = 9/4

Multiply both sides by 4 we have!!)

4x² + 4/x² = 9 × 4/4

4x² + 4/x² = 9

Therefore, 4x² + 4/x² = 9
