Quadratic Formula
Finds roots of a quadratic equation.
x = (−b ± √(b² − 4ac))/(2a)
Variables
- a,b,c
- coefficients of ax²+bx+c=0
Example
x²−5x+6=0 → x=2,3
How to use this formula
Identify the known values, keep units consistent, substitute the values into the formula, and calculate carefully. Then check whether the result is reasonable for the original problem.
