Answer 1

check your answer. when you answer not match the ask me .....

When take common last line

(x- 1/x) have left ........

Answer 2

${x}^{2} + \frac{1}{ {x}^{2} } - 2 - 3x + \frac{1}{x} \\ \\ = > {x}^{2} + \frac{1}{ {x}^{2} } - 2(x \times \frac{1}{2} ) - 3(x - \frac{1}{x} ) \\ \\ = > (x - \frac{1}{2} ) {}^{2} - 3(x - \frac{1}{x} ) \\ \\ = > (x - \frac{1}{x} )(x - \frac{1}{x} - 3)$
