Question : If $x^2+\frac{1}{x^2}=2$, then the value of $x-\frac{1}{x}$ is:
Option 1: –2
Option 2: 0
Option 3: 1
Option 4: –1
Correct Answer: 0
Solution : Given: $x^2+\frac{1}{x^2}=2$ We know that the algebraic identity is $(x-\frac{1}{x})^2=x^2+\frac{1}{x^2}-2$ Substitute the value of $x^2+\frac{1}{x^2}=2$ in the above expression, we get, $(x-\frac{1}{x})^2=2-2$ ⇒ $(x-\frac{1}{x})^2=0$ ⇒ $(x-\frac{1}{x})=0$ Hence, the correct answer is 0.
