A free quadratic equation calculator that shows and explains each step in solving your quadratic equation.
A quadratic equation is an equation ax2
+ bx + c = 0. In this equation, a, b, and c are constants. X is a variable which is not known. The constants a and b are called coefficients. Interestingly, a cannot equal 0 in the equation ax2
Finding a solution to a quadratic equation can appear challenging. However, you have this handy-dandy quadratic equation calculator. Acutally, quadratic equations can be reliably 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:
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 equal each other, resulting in one solution for x.
Quadratic equations are more than just mathematical flights of fantasy Quadratic equations are needed to calculate answers in many real-world fields, including engineering, pharmacokinetics and business.
The term "quadratic" comes from the Latin word quadratum,
which means "square." Why? Because what defines a quadratic equation is the inclusion of some variable squared. In our equation above, the term x2
(x squared) is what makes this equation quadratic.
