A free quadratic equation calculator that shows and explains each step in solving your quadratic equation.
A quadratic equation is any function that has the form: ax2
+ bx + c = 0. In this equation, x is an unknown, and a, b, and c are constants. A and b are referred to as coefficients. Further, a cannot equal to zero in the equation ax2
+bx+c=0. If a=0, then ax2
=0, and the equation becomes 0+bx+c=0, or bx+c=0. The equation bx+c=0 is a linear equation, and not a quadratic equation.
Solving a linear equation is relatively basic. Solving a quadratic equation requires some more advanced mathematics. Fortunately, you have this handy-dandy quadratic equation calculator. All kidding aside, quadratic equations can be quickly 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 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. Under extraordinary circumstances, the two roots may equal each other, meaning there will only be one solution for x.
Quadratic equations have real-life applications. Quadratic equations are needed to compute answers in many real-world fields, including physics, pharmacokinetics and architecture.
In our equation, a cannot be zero. However, b can be zero, and so can c.
