2. Warm Up 3/9/15 1.Do using long division and do again using synthetic division: (2x 3  10x 2  x  5)  (x  5) 2. Find S 7 for the series: 256, 64, 16, 4, ….

3. Warm Ups 3/10/15 3. Factor to find all the roots: x 4 – 5x 3 + 7x 2 – 5x + 6 = 0 4.If a 4 = 135 and a 6 = 1215, write the recursive and explicit formulas for the geometric sequence. What is the 10 th term of the sequence? Recursive: a n = a n- 1 insert pattern Explicit: a n = a 1 ∙r n-1

4. Reminder that the arithmetic explicit formula is: a n = a 1 + (n – 1)∙d
