Question

Check whether the following is quadratic equation or not.

x² + 6x − 4 = 0

Answer 1

Here it has been given that,

x² + 6x - 4 = 0

Now, the above equation clearly represents a quadratic equation of the form ax² + bx + c = 0, where a = 1, b = 6 and c = -4.

Hence, the above equation is a quadratic equation.
