प्रश्न
Check whether the following is quadratic equation or not.
`x-3/x=x^2`
उत्तर
Here it has been given that,
`x-3/x=x^2`
Now, solving the above equation further we get,
`(x^2-3)/x=x^2`
x2 - 3 = x3
-x3 + x2 - 3 = 0
Now, the above equation clearly does not represent a quadratic equation of the form ax2 + bx + c = 0, because -x3 + x2 - 3 = 0 is a polynomial of degree 3.
Hence, the above equation is not a quadratic equation.
