Question

Check whether the following is quadratic equation or not.

`x^2 - 2x - sqrtx - 5 = 0`

Solution

Here it has been given that,

`x^2 - 2x - sqrtx - 5 = 0`

Now, as we can see the above equation clearly does not represent a quadratic equation of the form ax2 + bx + c = 0, because `x^2 - 2x - sqrtx - 5 = 0` contains an extra term `x^(1/2)`, where 1/2 is not an integer.

Hence, the above equation is not a quadratic equation.

  Is there an error in this question or solution?
