Check whether the following equation is quadratic or not: x +https://static.philoid.co/ncertusercontent/solutions/user_files/63094/15042/images/extra-4_files/Image1134.gif = x 2 (x≠ 0).

Quadratic equation is an equation with degree 2

Multiply by x on both sides

x 2 +1=x 3


The degree of the given equation is 3.
∴ (x ≠ 0) is not a quadratic equation.
