Question

if x²+1/x=2=x+1/x² find the vlaue of x³+1/x² where x>0​

Answer 1

Answer:

x - 1/x = √3

Squaring on both sides:

x² + 1/x² - 2 = 3

Hence x² + 1/x² = 5

So the answer is 5.

Answer 2

Answer:

The answer is 3.

Step-by-step explanation:

x - 1/x = √3

Squaring on both sides:

x² + 1/x² = 3

Hence x² + 1/x² = 3

So the answer is 3.
