A free quadratic equation calculator that shows and explains each step in solving your quadratic equation.
A quadratic equation is any equation that can be written in the form: ax2
+ bx + c = 0, where x is an unknown, and a, b, and c are constants. A and b are referred to as coefficients. Interestingly, a cannot equal to 0 in the equation ax2
Finding a solution to a quadratic equation may appear daunting, because both x and x2
are unknown. Fortunately, there are a number of methods for solving quadratic equations. One of the most widely used is the quadratic formula
. The quadratic formula is:
Solving a quadratic equation will always result in 2 solutions for x. These solutions are called roots. These roots may both be real numbers or, they may both be complex numbers. Rarely, both roots may be equal, producing one solution for x.
Quadratic equations are an important part of mathematics. Quadratic equations are needed to find answers in many real-world fields, including physics, pharmacokinetics and business.
The quadratic equation calculator on this website uses the
quadratic formula to solve your quadratic equations, and this is a reliable and relatively simple way to do it. But there are other ways to solve a quadratic equation, such as completing the square or factoring.
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.
