Here is a worksheet that i need help on, please post work.List all possible rational zeros for each polynomial function.
P  x   3x 3  2x 2  5x  2
R  x   12x 3  17x 2  27x  30
Use Descartes rule of signs to describe the roots for each polynomial function.
m( x )  x 3  3 x 2  18 x  40
w ( x )  x 4  4 x 3  7 x 2  20 x  21
Find an upper bound and a lower bound for the zeros of the following polynomial functions.
h  x   x 4  2x 3  11x 2  14x  24
k  x   18x 3  9x 2  28x  12
