Question

Check whether the following is quadratic equation or not.

`x-3/x=x^2`

Solution

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.

  Is there an error in this question or solution?
