Works every time but it is difficult
quadratic formula
The quadratic formula is one of the more time consuming methods of solving a quadratic equation, but it works every time
It is a very complicated formiula
you will first have to put the equation in the form of this, then you can apply the quadratic formula by substituting values into a, b,and c:
What is a quadratic equation?
A quadratic equation always has two solutions, but sometimes the solutions are not real.
When you solve a quadratic equation, you usually have to find the variable x. In order to find this, you will have to put your equation in this form:
In order to find the variable x, you will have to substitute 0 into the variable y.
Graphing
When a quadratic equation is graphed, you will not see a straight line, but instead you will see a curve.
Unlike a linear line, there is two x intercepts instead of one
