A free quadratic equation calculator that shows and explains each step in solving your quadratic equation.
An equation that can be written as bx+c=0 is called a linear equation. It has one unknown, x, and 2 constants, b and c. If this equation were also to include the square of x as an unknown, it would become a quadratic equation. What is a quadratic equation? Any function that takes the form:
+ bx + c = 0,
where x is an unknown. A, b, and c are constants. The constants a and b are called coefficients. Also, it should be pointed out that a cannot be equal to zero.
Finding a solution to a quadratic equation may appear daunting. Fortunately, you have this handy-dandy quadratic equation solver. All kidding aside, quadratic equations can be readily 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. 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. Rarely, these two roots may be the same, meaning there will only be one solution for x.
Quadratic equations are an important part of mathematics. Quadratic equations are needed to calculate answers to many real-world problems. For example, to calculate 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 calculator 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.
