Question : If $K+\frac{1}{K}=-3$, then what is the value of $\left(\frac{K^6+1}{K^3}\right)+\left(\frac{K^4+1}{K^2}\right)$?
Option 1: 27
Option 2: – 29
Option 3: 29
Option 4: – 27
Correct Answer: – 29
Solution : Given equation, $K+\frac{1}{K}=-3$ ..........(1) Squaring the equation, we get, $(K+\frac{1}{K})^2=(-3)^2$ $K^2 + \frac{1}{K^2} + 2 = 9$ ⇒ $K^2 + \frac{1}{K^2} = 7$ ...........(2) Cubing equation (1), we get $(K+\frac{1}{K})^3 = (-3)^3$ ⇒ $K^3 + \frac{1}{K^3} + 3\cdot K\cdot\frac{1}{K}(K+\frac{1}{K}) = -27$ ⇒ $K^3+\frac{1}{K^3}+3(-3) =
