Check whether $3 x - 10 = 0$ is a quadratic equation or not?

Open in App

Solution

We know that the general form of quadratic equation is $a x^{2} + b x + c = 0$ .

The given equation is $3 x - 10 = 0$ in which the variable $x$ has degree $1$ and therefore it is not of the form $a x^{2} + b x + c = 0$ .

Hence, the equation $3 x - 10 = 0$ is not a quadratic equation, it is a linear equation.
