Thanks for the honesty! What was it that made you drop off? E.g. was it too long, or too much tedious algebra, or too much basics at the start?

- shatteredspace 5y agoI dropped off earlier than 45%, somewhere around 25%. It is about deriving the quadratic formula, not about 'what's a root'. What's a root could be a link you click on to give more information than a special x value when both side of the equation line up (a root is when the graph of a function crosses the x-axis). I like imagery and the clicking to progress to the next portion. What would be fantastic in my opinion is to take the step-by-step approach of something like WolframAlpha and apply it to defined topics with a set of defined examples rather than hey provide us an answer and if you get it wrong we will take you through a rudiment branch that will take us back to the main branch.
- jamesfisher 5y agoYeh, I think I tried to pack too much into the lesson. "What is a root" could be more like a prereq lesson. WA's step-by-step feature is amazing dark magic. I'd love to replicate that somehow ...
- DaemonAlchemist 5y agoI dropped off at about 70%. For me, it was a few things 1) Too much intro material - The explanation of what a root is was too long. By the time I got to the start of the derivation, my attention span was already running out, due to: 2) Too much tedious algebra - I felt annoyed that I needed to do a bunch of basic arithmetic to advance to the next section. 3) Complicated derivation - Like another commenter mentioned, I think the completing the square method would have been shorter and easier than this method.
