Question

If (x +1/x) ^2= 3, then (x^3 + 1/x^3) is equal to​

Answer 1

Answer:

2

Step-by-step explanation:

Let p (x) = x + 1 / x = 2  

= x + 1 = 2x

= 2x - x = 1

let g(x) = x^3 + 1/x^3

since, x = 1

therefore,

g (1) = (1)^3 +1 / (1)^3

= 1 + 1 / 1

= 2 / 1

= 2

So, the answer to your question is 2.
