A free quadratic equation calculator that shows and explains each step in solving your quadratic equation.
What is a quadratic equation? A quadratic equation is an function that has the form: ax2
+ bx + c = 0. In this equation, x is a variable which is not known, and a, b, and c are constants. The constants a and b, are referred to as coefficients. It is worth pointing out that a cannot be equal to 0 in the equation ax2
+bx+c=0. Otherwise, the equation ceases to be a quadratic equation, and becomes a linear equation.
Finding a solution to a quadratic equation may appear daunting, because both x and x2
are unknown. Fortunately, you have this handy-dandy quadratic equation solver. All kidding aside, quadratic equations can be always solved using the quadratic formula
, which is the same technique used by this quadratic equation solver. Try it, and it will explain each of the steps to you. Here is the quadratic formula:
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. Under extraordinary circumstances, these two roots may be the same, meaning there will only be one solution for x.
Quadratic equations are more than just mathematical flights of fantasy Quadratic equations are needed to compute answers in many real-world fields, including physics, biology and business.
The quadratic formula has been known for centuries. Brahmagupta, a mathematician from India, first described the quadratic formula as a means to calculate solutions to quadratic equations in the 7th Century AD.
