Answer 2

Answer:

$x^{2} + \frac{1}{x^{2} } = 34$

Step-by-step explanation:

$x + \frac{1}{x} = 6$

Square both sides.

$(x+\frac{1}{x} )^{2} = 6^{2} = 36$  --- (1)

Recall the identity:

$(a + b)^{2} = a^{2} + b^{2} + 2ab$

So, (1) becomes,

$x^{2} + \frac{1}{x^{2} } + 2x(\frac{1}{x} ) = 36$

$x^{2} + \frac{1}{x^{2} } + 2 = 36$

$x^{2} + \frac{1}{x^{2} } = 36 - 2 = 34$
