A free quadratic equation calculator that shows and explains each step in solving your quadratic equation.
A quadratic equation is an equation that can take the form: ax2
+ bx + c = 0, where x is a variable which is not known, and a, b, and c are constants. The constants a and b are called coefficients. Additionally, it should be noted that a cannot be equal to zero in the equation ax2
Finding a solution to a quadratic equation can appear daunting. However, you have this handy-dandy quadratic equation calculator. All kidding aside, quadratic equations can be readily 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:
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, the two roots may equal each other, meaning there will only be one solution for x.
Who cares? Why do we care about qudratic equations? Quadratic equations are needed to compute answers to many real-world problems. For example, to compute how an object will rise and fall due to Earth's gravity would require the use of s quadratic equation.
In our equation, a cannot be zero. However, b can be zero, and so can c.
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 using Quadratic-Equation-Calculator.com.
