Hi everyone,

My apologies for missing class today (my daughter is sick).  I missed you!  Your substitute Prof. Singh gave me an update – it sounds like he was able to cover repeated roots and complex roots, and you will get a chance to work on them in your WeBWorK assignments (due Tuesday).  I encourage you to post questions here, and I’ll do my best to respond.

In the meantime, if you are looking for additional help, I wanted to leave you with a few resources on these two topics (repeated roots / complex roots).

Paul’s Notes

These are very complete notes – they include an explanation of each rule, and several examples worked out. Here are links for his notes on repeated roots, and complex roots.

Videos

If you learn better by watching, you can check out these videos from PatrickJMT: an overview, with two examples (one with two real roots, one with repeated roots),  and an example with complex roots.

Best of luck,
Prof. Reitz
