Option 1: 20

Option 2: 30

Question : If $5 x-\frac{5}{x}+6=0$, then $x^2+\frac{1}{x^2}$ is:

Option 1: $\frac{86}{25}$

Option 2: $\frac{43}{12}$

Option 3: $\frac{81}{10}$

Option 4: $\frac{86}{11}$

Team Careers360 5th Jan, 2024

Correct Answer: $\frac{86}{25}$


Solution : Given, $5 x-\frac{5}{x}+6=0$
$⇒5(x-\frac{1}{x})+6=0$
$⇒x-\frac{1}{x}=-\frac{6}{5}$
Squaring both sides, we get:
$⇒x^2+\frac{1}{x^2}-2=\frac{36}{25}$
$⇒x^2+\frac{1}{x^2}=\frac{36}{25}+2$
$\therefore x^2+\frac{1}{x^2}=\frac{86}{25}$
Hence, the correct answer is $\frac{86}{25}$.​​​
