A free quadratic equation calculator that shows and explains each step in solving your quadratic equation.
A quadratic equation is an function that can be written as: ax2
+ bx + c = 0. In this equation, x is an unknown, and a, b, and c are constants. The constants a and b, are referred to as coefficients. Furthermore, it should be pointed out that a cannot be equal to 0.
Solving a linear equation is simple. Solving a quadratic equation is less straightforward. Fortunately, you have this handy-dandy quadratic equation calculator. All kidding aside, quadratic equations can be quickly 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. Under extraordinary circumstances, the two roots may be equal, producing one solution for x.
Who cares? Why do we care about qudratic equations? Quadratic equations are needed to calculate answers in many real-world fields, including physics, pharmacokinetics and business.
In our equation, a cannot be zero. However, b can be zero, and so can c.
We this quadratic equation solver is useful to you. We hope the explanations showing how you can solve the equation yourself are educational and helpful. But we totally understand if you just want to use it to find the answers you're looking for. Thank you for using Quadratic-Equation-Calculator.com.
