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.
We used the remainder theorem to show that (x+5) was indeed a factor!

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)
