Check Whether the Following is Quadratic Equation Or Not. X^2+1/X^2=5 - CBSE Class 10 - Mathematics

Question

Check whether the following is quadratic equation or not.

x^2+1/x^2=5

Solution

Here it has been given that,

x^2+1/x^2=5

Now, solving the above equation further we get,

(x^2+1)/x^2=5

⇒ x5x2

⇒ x− 5x2 0

Now, the above equation clearly does not represent a quadratic equation of the form ax2 + bx + c = 0, because x− 5x2 0 is a polynomial of degree 4.

Hence, the above equation is not a quadratic equation.

Is there an error in this question or solution?
