To use the online calculator, go to: http://matrixlab-examples.com/quadratic-equation-solver.html To download the presentation, go to: http://www.slideshare.net/matrixlab/quadratic-equations-10597333 This is the general form of the 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!
