Question

If x+1/x=6 find value of x2+1/x2

Answer 1

Step-by-step explanation:

x^2 + 1/x^2 = ( x+1/x) ^2 -2

= 36-2 = 34

Answer 2

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

Step-by-step explanation

Given equation

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

square on both the sides

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

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

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