This means that the highest power of the variable x is 2. This is the form where one side of the equation is zero, and all other terms are gathered on the opposite side.Ī quadratic equation contains only second-degree polynomials. The form above is known as the standard form of a quadratic equation.

What Is A Quadratic Equation?Ī quadratic equation is an equation that can be rearranged (using rules of algebra) into the form

There are three basic cases for the solutions when solving a quadratic equation (more on this later).įor now, let’s start with quadratic equations: what they are, what they look like, and how to recognize them. The amazing thing is: no matter which quadratic equation you choose, the quadratic formula will tell you the solutions (you can learn more about what the solutions of a quadratic formula represent in my article here). However, there is only one quadratic formula. There are many possible quadratic equations (in fact, there are infinitely many!). We’ll also look at some examples and how to apply the equation in different scenarios. In this article, we’ll take a closer look at the difference between a quadratic equation and the quadratic formula. In fact, the quadratic formula is a shortcut for this method! Of course, there are other ways to solve a quadratic equation, such as completing the square. The quadratic formula uses the coefficients a, b, and c from the quadratic equation to help us find these solutions. So, what is the difference between a quadratic equation and the quadratic formula? A quadratic equation has the standard form ax 2 + bx + c = 0, and it can have two real solutions, one real repeated solution, or two complex conjugate solutions. Quadratic equations appear often in algebra, and they need to be solved! The quadratic formula helps you to do this – but sometimes it is confusing to remember the difference between these two ideas.
