Question 951146
Use synthetic division to find the upper bound of polynomial (x^4-x^3-7x^2+x+6) please show all work!! I need to see what the desired result looks like in synthetic division.
***
Use the rational roots theorem with synthetic division:

...0..|.....1......-1......-7......1.......6..........
...1..|.....1.......0......-7.....-6.......0 (1 is a root)
=======================
...0..|.....1.......0......-7.....-6
...2..|.....1.......2......-3....-12
...3..|.....1.......3.......2......0 (3 is a root)
...4..|.....1.......4.......9......30 (4 is an upper bound, all numbers positive)
P(x)=(x-1)(x-3)(x^2+3x+2)
P(x)=(x-1)(x-3)(x+1)(x+2)
