1. Warm-Up: Find the slope between: (5, 8) & (-2, 4)
HW: Slide & Divide HW #s 16-24
Big quiz on Friday (counts as ½ a test grade!)
Warm-Up:
Find the slope between: (5, 8) & (-2, 4)
Change the equation into slope-intercept form: y – 5 = ½(x + 4)

2. Today’s Lesson:
Factoring trinomials when the leading coefficient does not equal 1
January 27, 2014

3. 𝑎𝑥 2 +𝑏𝑥+𝑐 Recall Standard Form
We can factor this if a = 1 but what is a ≠ 1?
Once again there are many methods but we will just go over one method today!

4. S F D R S Slide & Divide Method wedish ish on’t eally wim
Step 1: S- Slide
Step 2: F- Factor
Step 3: D- Divide
Step 4: R- Reduce
Step 5: S- Swing
There is Mnemonic device used for the
steps to Factor a polynomial of three terms
using this method it is…….. F
ish D
on’t R

5. Slide & Divide 6x2 – 19x + 15
STEP 1: SLIDE - slide the leading coefficient over to the c term and multiply. Then FACTOR like normal.

6. Slide & Divide 6x2 – 19x + 15
Step 2: DIVIDE – place the original leading coefficient (6) under the numbers you chose (like the 6 is dividing) and then REDUCE.

7. Slide & Divide 6x2 – 19x + 15
Step 3: Since neither fraction simplified to a whole number, SWING the denominator in front of each x :

8. Factor 2x2 + 7x + 6.
