Check whether the following is quadratic equation or not.
`x+1/x=x^2`, x ≠ 0
Here it has been given that,
Now, solving the above equation further we get,
x2 + 1 = x3
-x3 + x2 + 1 = 0
Now as we can see, the above equation clearly does not represent a quadratic equation of the form ax2 + bx + c = 0, because -x3 + x2 + 1 is a polynomial having a degree of 3 which is never present in a quadratic polynomial.
Hence, the above equation is not a quadratic equation.
