What is the general formula for quadratic equation?

ax²+bx+c=0
The general form of a quadratic equation is given by: ax²+bx+c=0, where a, b, and c are coefficients and x is the unknown variable.

How do you set up a quadratic equation?

The quadratic formula helps us solve any quadratic equation. First, we bring the equation to the form ax²+bx+c=0, where a, b, and c are coefficients. Then, we plug these coefficients in the formula: (-b±√(b²-4ac))/(2a) . See examples of using the formula to solve a variety of equations.
