1st, 2nd, 3rd Hours:
Bellwork gave students practice finding real solutions by graphing and using these solutions and polynomial division to find the imaginary solutions.
The remainder of the period we finished discussing Sec 6-3 by covering the topics of the Remainder Theorem and Synthetic Division.
Hwk #31 is due tomorrow. Sec 6-3
Page 324. Problems 11, 12, 23, 28, 29, 43, 44. For #23 use polynomial division only. For #’s 28 & 29 use Remainder Theorem only.
