Penjelasan dengan langkah-langkah:
[tex]x + \frac{1}{x} = 6[/tex]
[tex] \: [/tex]
[tex] {(x + \frac{1}{x} )}^{2} = {6}^{2} [/tex]
[tex](x + \frac{1}{x} )(x + \frac{1}{x} ) = 36[/tex]
[tex] {x}^{2} + 1 + 1 + \frac{1}{ {x}^{2} } = 36[/tex]
[tex] {x}^{2} + 2 + \frac{1}{ {x}^{2} } = 36[/tex]
[tex] {x}^{2} + \frac{1}{ {x}^{2} } = 36 - 2[/tex]
[tex] {x}^{2} + \frac{1}{ {x}^{2} } = 34[/tex]
