It is important in mathematics to always use the proper
use the proper mathematical notation for all Worksheet problems.
1. Use synthetic division to divide P(x) = 2x4 - x3 -
6x2 + 7x - 2 by
d(x) = x + 1, and write P(x) in the form P(x) = Q(x) ·
d(x) + r(x).
2. Use the Rational Root Theorem to find the possible
zeros of P(x), and
use synthetic division to find all the zeros. Be sure to check for multiple
zeros , and state the multiplicity of each zero .
3. Write P(x) as a product of linear factors.
4. Sketch the graph of P (x) = 2x4 - x3 - 6x2 + 7x - 2. Be sure
all the zeros , and the y- intercept .
