# Remainder Theorem INB 90 1/14/13

INB 81 – ACT Geometry Review:

Monday 1/14/13 In Class Notes / Examples:

Friday we “discovered” that we could substitude “a” into our polynomial and the result would be the remainder if we divided by (x-a).

Today, we’re answering the question “When we use  Remainder Theorem, what is this really telling us?”

INB page 90 “More Remainder Theorem” We graphed the given polynomial as a function in our graphing calculators. Noted the x-intercepts. “Created” factors from our x-intercepts, then graphed our factors to see the graphed resulted in the same thing. Assignment/Practice due Tuesday: # Geometry 1/10/13

INB 15 Segments & Midpoints INB 14 Part 1 Processing Midpoints of Segments (boss/secretary) Part 2 Segment Addition practice page 8

INB 17 Midpoints with Coordinates After some sharing of how to find the midpoints with graph paper – another student suggested he added the coordinates, then divided by 2.

Find M, the midpoint of AB.  A(7, 3) and B (13, 5)…

x-coordinates:  7+13=20 / 2 = 10 and y-coordinates:  3 + 5 = 8 / 2 = 4 so the midopint will be M(10, 4)
