Question

3check whether x square + 1 /x square=2 is the quadratic equation
or not​

Answer 1

$\huge \mathfrak \color{pink}{Answer}$

To find,

whether x² + 1/x² = 2 is a quadratic equation or not.

x² + 1/x = 2

=> x² + 1/x² = 2

=>( x⁴ + 1 )x² = 2

=> x⁴ + 1 = 2x²

=> x⁴ - 2x² + 1 = 0

Since,

The power of 'x' is 4 and it is not given in the form of ax² + bx + c = 0

Therefore,

IT is not a quadratic equation
