A free quadratic equation calculator that shows and explains each step in solving your quadratic equation.
A quadratic equation is an equation that can be written in the form:
+ bx + c = 0,
where x is an unknown, and a, b, and c are constants. The constants a and b, are referred to as coefficients. Additionally, it is worth noting that a cannot be 0.
Solving a linear equation is straightforward. Solving a quadratic equation requires more work. Fortunately, you have this handy-dandy quadratic equation solver. All kidding aside, quadratic equations can be quickly 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:
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. Depending on the values of a, b, and c, both roots may be the same, producing one solution for x.
Quadratic equations are more than just mathematical mumbo-jumbo 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 this quadratic equation solver is useful to you. We encourage you to try it with different values, and to read the explanation for how to reach your answer. But, if you just want to use it to calculate the answers to your quadratic equations, that's cool too. Thank you for your interest in Quadratic-Equation-Calculator.com.
