We will have a 4th quarter final. Our warm-ups
this quarter will be the final exam review. It is
comprehensive; keep good notes so you can
prepare for the final.
Credit for classes is given on a semester basis.
Even if you failed the 3rd quarter, you can still
receive credit for the 2nd semester if your average
grade is 63%
3. Warm-Up/Review:
Today’s warm-up will focus on our current unit,
quadratic equations & functions.
Solve: −4𝑥2
+ 23x + 6
What is your strategy? What method will you use to
solve? Why? Or maybe you’re thinking, “What does
it mean to solve?”
Completing the square would be difficult here
because of the b term. The better strategy would be
to try to solve by factoring first.
7. Warm-Up/Review:
Solve or write no solution
6x2
- 54 = 0 Solve by..........? Finding square roots
One clue is ......what? Lack of a ‘b’ term x = + 3
x2
- 108 = 0 x =
Must factor out all perfect
squares next.
