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: $\frac{\mathrm{K}^4-8 \mathrm{~K}^2+32}{16}$

Team Careers360 25th Jan, 2024

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:
$⇒\left(x^2 + \frac{1}{x^2}\right)^2 = \mathrm{\left(\frac{K^2}{4} - 2\right)^2}$
$⇒x^4 + 2 + \frac{1}{x^4} = \mathrm{\left(\frac{K^2}{4} - 2\right)^2}$
