Question

If x = 4 - √15, find the value of (x + 1/x)² - (x - 1/x)²

Answer 1

Answer:

Final Answer is = 2

Final Answer is = 2Step-by-step explanation:

Final Answer is = 2Step-by-step explanation:= (x² + 1)²/x² - (x² - 1)²/x²

Final Answer is = 2Step-by-step explanation:= (x² + 1)²/x² - (x² - 1)²/x²= X² + 1 - X² + 1 / X²

Final Answer is = 2Step-by-step explanation:= (x² + 1)²/x² - (x² - 1)²/x²= X² + 1 - X² + 1 / X²= 2/x²

Final Answer is = 2Step-by-step explanation:= (x² + 1)²/x² - (x² - 1)²/x²= X² + 1 - X² + 1 / X²= 2/x²= x = 4 - √15

Final Answer is = 2Step-by-step explanation:= (x² + 1)²/x² - (x² - 1)²/x²= X² + 1 - X² + 1 / X²= 2/x²= x = 4 - √15= 2 / (4 - √15)²

Final Answer is = 2Step-by-step explanation:= (x² + 1)²/x² - (x² - 1)²/x²= X² + 1 - X² + 1 / X²= 2/x²= x = 4 - √15= 2 / (4 - √15)²= 2 / (16 - 15 )

Final Answer is = 2Step-by-step explanation:= (x² + 1)²/x² - (x² - 1)²/x²= X² + 1 - X² + 1 / X²= 2/x²= x = 4 - √15= 2 / (4 - √15)²= 2 / (16 - 15 )= 2/1

Final Answer is = 2Step-by-step explanation:= (x² + 1)²/x² - (x² - 1)²/x²= X² + 1 - X² + 1 / X²= 2/x²= x = 4 - √15= 2 / (4 - √15)²= 2 / (16 - 15 )= 2/1= 2
