#Factor a quadratic equation how to#

In fact, we complete the square for the standard form of the quadratic equation in order to derive the quadratic formula. The quadratic formula is a shortcut for the method of completing the square. ( If you are confused by the difference between a quadratic equation and the quadratic formula, this article will help).

ax 2 + bx + c = 0 (where a is not zero).

The quadratic formula gives the solution for the standard form of the quadratic equation

Problems that involve gravity (tracking the position of falling objects).

Finding roots of a quadratic equation (when it is difficult to factor).

Finding zeros of a parabola (finding the x-intercepts on the graph of a quadratic).

The quadratic formula is used in several different scenarios in math and physics, including: We’ll also take a look at some examples to illustrate the idea. In this article, we’ll talk about when to use the quadratic formula. Of course, there are certain situations when factoring is easier than using the quadratic formula. In addition, the quadratic formula is useful in physics to deal with gravity and falling objects. You can also use the quadratic formula to find the roots of a quadratic equation if factoring is difficult.

So, when do you use the quadratic formula? You can use the quadratic formula to find the zeros (x-intercepts) of a parabola. The quadratic formula is one method that helps you to solve these equations.
