Polynomials: test prep/review Part 1 of 2

Correction to #6: At 10:48 - 11:54 mark please change to + 15x - 1 x. The resulting factors will be

5x^4 + 15x^2 = 5x^2(x^2 + 3) &
-1x^2 - 3 = -1(x^2 + 3).

This yields (x^2 + 3)(5x^2 - 1) which cannot be factored further.

Part 1. Here's a 20-question test review packet shared by one of my students.

You can't get more unedited than this.
