This quadratic formula calculator lets you calculate the discriminant and the roots or solutions for a quadratic equation. The results will appear in the boxes labeled Root 1 and Root 2.
Enter the corresponding values into the boxes below and click Solve. The user might also be interested in using some plotting tools to visualize the function and its solutions. How to Use the Quadratic Equation Calculator. Moreover, it is preferable (not a prerequisite) to be familiar with complex numbers since the solution of a quadratic equation might be a pair of complex numbers. While using the tool is straightforward, the user should be able to perform basic arithmetic operations to put the equation in the standard quadratic form ax²+bx+c=0 to use the tool. Quadratic functions can be found in engineering, economics, agriculture, etc. The quadratic formula calculator is designed for students in schools and universities or anyone looking for a quick solution to a quadratic function. The coefficient a a is the coefficient that appears multiplying the quadratic. Examine the given equation of the form ax2+bx+c ax2 +bx+c, and determine the coefficients a a, b b and c c. $$x₁=\frac = 2 ± 2i$$ Scope of Use and Tips There are several steps you have to follow in order to successfully solve a quadratic equation: Step 1: Identify the coefficients. One way to solve a quadratic function is using the quadratic formula stated in equation (1). The quadratic formula gives solutions to the quadratic equation ax2+bx+c0 and is written in the form of x (-b (b2 - 4ac)) / (2a) Does any quadratic equation have two solutions There can be 0, 1 or 2 solutions to a quadratic equation. A quadratic equation can have a maximum of two solutions in this context. The number of possible solutions to an equation equals the highest exponent value in the equation. As shown in the previous examples, the values of A, B, and C can be positive/negative integers or decimals (fractions) such that a≠0. However, 2x+3=0 does not represent a quadratic equation since the quadratic term ax² is not found in the equation. The equation 2x²=0 is also a quadratic equation, with b=0 and c=0. We can show some examples of quadratic equations below. The word "quad" or "second-degree" comes from the fact that the highest exponent of the variable x is 2, as in x². The terms a and b are the coefficients of x² and x, respectively, while C is a constant.
Quadratic EquationsĪ quadratic equation sometimes referred to as a quadratic function or second-degree polynomial, is an algebraic equation with a general form of ax²+bx+c=0 where x is an unknown variable to be found. Consequently, the user will conceptualize the problem solving, numerical results, and a step-by-step guide through the solution.
