Quadratic Equation Solver - Formula

To use the online calculator, go to: http://matrixlab-examples.com/quadratic-equation-solver.html

I'm gonna show you how to use the quadratic formula.

This is the general form of quadratic equations. You have to take care of 3 coefficients: a, b and c. The formula produces two solutions to each problem.

The quadratic coefficient is called a, the linear coefficient is called b, and the free term is called c.

In this example, our quadratic coefficient is 2, our linear coefficient is 3, and the free term is 1.

The first solution is -.5 and the second solution is -1.

Now, let's use the calculator that we have for this purpose. We just fill in the blanks, first a, then b and finally c. We can see the two solutions, in this case -0.5 and -1.

And we can explore solutions for other coefficients, even for complex solutions.

Thank you for watching!
