# Check Whether the Following is Quadratic Equation Or Not. (X+1/X)^2=3(1+1/X)+4 - CBSE Class 10 - Mathematics

#### Question

Check whether the following is quadratic equation or not.

(x+1/x)^2=3(1+1/x)+4

#### Solution

Here it has been given that,

(x+1/x)^2=3(1+1/x)+4

Now, solving the above equation further we get,

((x^2+1)/x)^2=(3x^2+1+4x)/x

Now as we can see, the above equation clearly does not represent a quadratic equation of the form ax2 + bx + c = 0, because x4 - 3x3 - 2x2 - x + 1 is a polynomial having a degree of 4 which is never present in a quadratic polynomial.

Hence, the above equation is not a quadratic equation.

Is there an error in this question or solution?
