How to Solve Mathematical Equation in LabVIEW - Creating SubVI

In this video, I will show two different aspects of LabVIEW.
1- How to use mathematical tools of LabVIEW and by using some of them I will show how to solve the quadrative equation in LabVIEW.
2- After solving the quadratic equation I will show how can you create subVI of a quadratic equation that can be later used anywhere when ever you want.
the advantage of subvi is that you don't need to create the, again and again, same code, just use your subvi, as in this case use SubVI of quadratic equation instead of doing the same coding again.
