Binomial Theorem

While I expect you would have copied this question down in class, here’s the question we were looking at on Thursday.

Find the coefficient of \(x^2\) in the expansion of

  1. \((2-x)(5x+3)^7\)
  2. \((2-x)^3(5x+3)^7\)

Answers can be checked using the CAS functionality of GeoGebra.

Sequences and Series Test

As discussed this past week, we’ll have a test on Sequences and Series on Tuesday the 19th. In addition to the questions you’ve already done on this material, the following questions should help you prepare for the test.

Pages 200–205 questions 1, 3, 8, 9, 10, 13, 18, 21, 25, 27, 39, 40, 43
