Question

Check whether the following is quadratic equation or not.

`x + 1/x = 1`

Answer 1

Here it has been given that,

`x+1/x=1`

Now, solving the above equation further we get,

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

x² + 1 = x

x² - x + 1 = 0

Now as we can see, the above equation clearly represents a quadratic equation of the form ax² + bx + c = 0, where a = 1, b = -1 and c = 1.

Hence, the above equation is a quadratic equation.
