Step-by-step explanation:

$x+\frac{1}{x} =6 , x^{2} +\frac{1}{x^{2} } =?$

squaring both side -

$(x+\frac{1}{x} )^{2} =(6)^{2} \\:(x+y)^{2} =x^{2} +2xy+y^{2} \\(x)^{2} +2*x*\frac{1}{x} +(\frac{1}{x} )^{2} =36\\ x^{2} +2+\frac{1}{x^{2} }=36\\x^{2} +\frac{1}{x^{2} } =36-2\\x^{2} +\frac{1}{x^{2} } =34$
