Question : If $x+\frac{1}{x}=\mathrm{\frac{K}{2}}$, then what is the value of $\frac{x^8+1}{x^4} ?$
Option 1: $\frac{\mathrm{K}^4-16 \mathrm{~K}^2+32}{16}$
Option 2: $\frac{\mathrm{K}^4-8 \mathrm{~K}^2-36}{32}$
Option 3: $\frac{\mathrm{K}^4-8 \mathrm{~K}^2-32}{16}$
Option 4: $\frac{\mathrm{K}^4-8 \mathrm{~K}^2+32}{16}$
Correct Answer: $\frac{\mathrm{K}^4-16 \mathrm{~K}^2+32}{16}$
Solution : $x + \frac{1}{x} = \frac{K}{2}$ $⇒\left(x + \frac{1}{x}\right)^2 = \mathrm{\left(\frac{K}{2}\right)^2}$ $⇒x^2 + 2 + \frac{1}{x^2} = \mathrm{\frac{K^2}{4}}$ $⇒x^2 + \frac{1}{x^2} =\mathrm{ \frac{K^2}{4} - 2}$ Now, square this equation: $⇒\left(x^2 + \frac{1}{x^2}\right)^2 = \mathrm{\left(\frac{K^2}{4} - 2\right)^2}$ $⇒x^4 + 2 + \frac{1}{x^4} = \mathrm{\left(\frac{K^2}{4} - 2\right)^2}$
