A free quadratic equation calculator that shows and explains each step in solving your quadratic equation.
A quadratic equation is any equation
+ bx + c = 0.
\ In this equation, a, b, and c are constants. X is an unknown. A and b are referred to as coefficients. It should be pointed out that a cannot equal to zero.
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
. This is the quadratic formula:
Since there are always 2 solutions to a square root (one negative, one positive), solving the quadratic equation results in 2 values for x. The two solutions for x (which may be positive or negative, real or complex) are called roots. Under extraordinary circumstances, these two roots may be the same, producing one solution for x.
Why do we need to be able to solve quadratic equations? Quadratic equations are needed to find answers to many real-world problems. The geometry of a parablolic dish antenna is one example of an application of quadratic equations.
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.
We hope you find this quadratic equation solver useful. We encourage you to plug in different values for a, b, and c. But we totally understand if you just want to use it to find the answers you're looking for. Thank you for your interest in Quadratic-Equation-Calculator.com.
