In addition to the
textbook, I’ve put together a
complete power point
covering all the topics in the
unit.You can find it on the right
side of the homepage with
the practice tests and
additional questions
49 slides with
definitions, practice
questions, and step-by-
step instructions.

6. Warm-Up/Review:
Find the actual dimensions of the rectangle:
x + 5
x - 1A = 112
(x + 5) (x – 1) = 112
x2
+ 4x - 5 = 112
x2
+ 4x + 4 = 121
(x + 2) 2
= 121
x = 2 + 11 x = 13, x = -9
x2
+ 4x = 117
7. Pencils down, mental math only. What is the resulting
trinomial?
Warm-Up/Review:
Square, Double, Square
9m2 – 42mn + 49n
Don’t say anything for at least one minute. Think, work first
8. 1. Write the equation for each graph given its change
from the parent graph: y = x2
a. 2 units down
Review: Solving Quadratic Equations

any to ‘a’ above?
2. Write the equation for this
parabola in both factored and
standard forms.
Factored Form: (x + 4) (x + 2)
Standard Form: (x2 + 6x + 8)
9. Warm-Up/Review:
x = 0, x = 4
Find the zero’s of the function (Complete the square)
-(x + 2) = + 2
tells direction only
10. Warm-Up/Review:
Nolan earned 5% interest per year on the money he kept
in the bank. After one year he had earned $20 in interest.
How much money did he have in the bank?
56.76 x 1010 = 5.676 x 1011
We don’t know the original amount, and the amount
increased. Therefore... 20 ÷ .05 = $400
