Today:
Warm-Up:
Review GCF, Prime Factorization, and Factoring
Class Work from Monday
Test: Properties & Proofs--Last 15 min. of class

2. Warm-Up:

3. Warm-Up:
Reduce the fraction, if possible, by using prime factorization to
find the GCF of:
GCF = 2 x 3 = 6
144/6 = 24
150/6 = 25
GCF = 7 x 5 = 35
140/35 = 4
245/35 = 7
Simplify Using GCF: 48x3 y4z = 24•3•xxx•yyyy•z
56xy5z3 = 23•7•x•yyyyy•zzz

4. Warm-Up:
48x3 y4z
Please note: If an expression has a single term,
56xy5z3
simplifying is accomplished by reducing ; (GCF)
3c - 24
If an expression has more than one term, c - 8
simplifying is accomplished by factoring (GCF again)
Simplify by factoring:
2a + 6
And Lastly,
4a - 12

5. Before Test:
Work on/Complete
4-4, and {8-2(don't do #'s 19-30)}
Do odd # problems on one side and
even #’s on the other

6. Test Question Changes
--Should read: 6 • 1/6 = 1
Remove the negative
--#4: 12 - 3x = 14 - 5x
12 - 3x + 5x = 14 - 5x + 5x
