JavaScript Quadratic Equation Solver Program for Beginners (Programming Mathematics)

In this video, I will walk you through some lines of codes that will help a beginner to understand how a simple web driven JavaScript program will help to solve Quadratic Equations. This does not require a pre knowledge of any programming language, but the viewer must have interest thinking around codes. We could have written this program with Java, C, C++, Python, or any order programming language, which we are going to do in subsequent videos. The use of JavaScript prompt() and alert() functions will help us in this simple Quadratic Equation Solver.

I left off validating the user input in this video to keep the program as simple as possible for a beginner and not to overwhelm you with too many new functions and lines of codes. But in subsequent videos, I will gradually increase the complexity.

To refresh your mathematics memory on decimal numbers and significant figures, which I used in this video to format the final answer, I have left a link below this description for your considerations.
