Check whether the equation is quadratic or not? x*2+1/x*2 =2

1.	Check whether the equation is quadratic or not? x2+1/x2 =2
Answer» We have,x2 +\xa0{tex}\\frac{1}{x^2}{/tex}\xa0= 0{tex} \\Rightarrow{/tex}\xa0x4\xa0- 1 = 0{tex} \\Rightarrow{/tex}\xa0x4\xa0- 1 = 0and (x4\xa0- 1) is a polynomial of degree 4. It is also not in the form of\xa0{tex}ax^2+bx+c=0{/tex}{tex}\\therefore{/tex}\xa0Given equation\xa0is not a quadratic equation.
