Then we plug these coefficients in the formula. Once you know the formula you need to know how to determine the numbers to insert. Given a general quadratic equation of the form.
In elementary algebra the quadratic formula is a formula that provides the solutions to a quadratic equationThere are other ways of solving a quadratic equation instead of using the quadratic formula such as factoring direct factoring grouping AC method completing the square graphing and others.
A quadratic equation as you remember is an equation that can be written on the standard form a x 2 b x c 0 w h e r e a 0 You know by now how to solve a quadratic equation using factoring. That is one solution to the equation or you can add 7 to both sides of that equation and you get s is equal to 7. A quadratic equation is a polynomial equation of degree 2. Example Click to try 2 x 2 5 x 3 0 About the quadratic formula Solve an equation of the form a x 2 b x c 0 by using the quadratic formula.
