Question 364534: Use synthetic division to verify the upper bound and lower bound of the zeros of f.
f(x) = 2x^4 -8x +3
Upper bound: x= 3; Lower bound: x= -4
The quotient I found for the upper bound was 2x^3 + 6x^2 + 18x + 46 + 136/ x-3
I have no idea if this is right and I am not sure where I would need to go from here.

3)....2....0....0....-8....3
.......2.....6...18....46....|..141

So f(3) = 141
-----
-4)....2....0....0....-8....3
........2....-8....32....-136....|..547
---
So f(-4) = 547
