1) [MGSE9-12.N.CN.9] Using the Rational Root Theorem, list all possible rational roots for the function f(x)= 5x3 + 4x + 14
2) [MGSE9-12.N.CN.9] According to the Fundamental Theorem of Algebra, how many roots does the polynomial
3x 4  7 x 3  24 x  15 have?
3) [MGSE9-12.A.APR.2] Is -2 a root of p( x)  x 3  5x 2  10 x  30 ?
4) [MGSE9-12.A.APR.2] Arnold is attempting to find factors of the polynomial f ( x)  x 3  5x 2  x  5 by applying the
Remainder Theorem. He used synthetic division and the results are shown below. Based on the results of the synthetic
division, what can Arnold conclude?
5 1  5 1 5
5
0 5
1 0 1 0
(A) ( x  5) is a factor because the remainder is zero.
(B) ( x  5) is a factor because the remainder is not zero.
(C) ( x  5) is not a factor because the remainder is not zero.
(D) ( x  5) is a factor because the remainder is zero.
