Quadratic Solver

Quadratic Solver is a simple-to-use app that provides math students with a quick method of solving quadratic equations. It supports graphs and contains a couple of options that can be seamlessly configured, even by those not accustomed to this sort of software.

Outdated, yet functional tool

By the look of the installer that takes us back to Windows 98, due to the fullscreen window with the solid background color, it's quite obvious that Quadratic Solver hasn't received updates for a very long time. However, the setup is quick and uneventful.

Calculate quadratic expressions

The GUI is user-friendly. The central window has a simple design and layout, showing the quadratic expression in the form of ax^2 + bx + c and an example, along with four buttons for performing calculations, plotting graphs, finding a value of y, and changing the accuracy.
It's necessary to enter the a, b and c values and find out the solution with the x and y values. The tool crashes if the quadratic doesn't have a solution.

View graphs, find y, and set the accuracy

Moreover, you can examine its graphical representation while keeping in mind that the x and y coordinates aren't marked. To find out the value of y, you just have to specify x. Furthermore, the expression's accuracy can be set to 0, 1 or 3 instead of 2 decimal places.
There are no other notable options implemented by this app. Unfortunately, it doesn't have features for printing information, exporting it to file, or copying it to the Clipboard for closer investigation.

Evaluation and conclusion

Although Quadratic Solver hasn't been updated for a long time, it didn't have compatibility issues with the latest Windows edition in our tests. It calculated quadratic expressions fast while remaining light on system resources usage. Thanks to its straightforward options, it can be easily used.
