Question : If $x=3+2\sqrt{2}$, then $\frac{x^{6}+x^{4}+x^{2}+1}{x^{3}}$ is equal to:
Option 1: 216
Option 2: 192
Option 3: 198
Option 4: 204
Correct Answer: 204
Solution : Given: $x=3+2\sqrt{2}$ -----------------(i) $\frac{x^{6}+x^{4}+x^{2}+1}{x^{3}}$ = $\frac{x^{6}}{x^{3}}$ + $\frac{x^{4}}{x^{3}}$ + $\frac{x^{2}}{x^{3}}$ + $\frac{1}{x^{3}}$ = $x^{3} + x + \frac{1}{x} + \frac{1}{x^{3}}$ = $x^{3} + \frac{1}{x^{3}} + x + \frac{1}{x}$ Using identity: $(a+b)^3 = a^3+b^3+3ab(a+b)$ Now, $\frac{x^{6}+x^{4}+x^{2}+1}{x^{3}}= (x + \frac{1}{x})^{3} - 3(x + \frac{1}{x})+(x + \frac{1}{x})$ =
