A free quadratic equation calculator that shows and explains each step in solving your quadratic equation.
What is a quadratic equation? Any equation that can be written in the form:
+ bx + c = 0.
\ In this equation, a, b, and c are constants. X is unknown. The constants a and b, are referred to as coefficients. Furthermore, it is worth pointing out that a cannot be equal to 0. Otherwise, the equation ceases to be a quadratic equation, and becomes a linear equation.
Compared to solving a linear equation, solving a quadratic equation requires a few more steps. However, you have this handy-dandy quadratic equation calculator. All kidding aside, quadratic equations can be always solved using the quadratic formula
, which is the same technique used by this quadratic equation calculator. Try it, and it will explain each of the steps to you. The quadratic formula is written:
When you compute a solution to a quadratic equation, you will always find 2 values for x, called "roots". These roots may both be real numbers or, they may both be complex numbers. Depending on the values of a, b, and c, both roots may be equal, meaning there will only be one solution for x.
Quadratic equations are an important part of mathematics. Quadratic equations are needed to compute answers in many real-world fields, including physics, biology and business.
In our equation, a cannot be zero. However, b can be zero, and so can c.
