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. A quadratic equation is an function that can be written as:
+ bx + c = 0.
\ In this equation, a, b, and c are constants. X is a variable which is not known. A and b are referred to as coefficients. Also, a cannot equal to 0 in the equation ax2
Finding a solution to a quadratic equation may appear daunting, because both x and x2
are unknown. However, there are a number of methods for solving quadratic equations. One of the most widely used is the quadratic formula
. This is the quadratic formula:
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. Rarely, these two roots may be equal, producing one solution for x.
Quadratic equations have real-life applications. Quadratic equations are needed to calculate answers to many real-world problems. For example, to calculate whether a braking car can stop fast enough to avoid hitting something 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 hope the explanations showing how you can solve the equation yourself are educational and helpful. 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.
