A. 6 C. 14.4
B. 10 D. 20
20. Use the remainder theorem and the factor theorem to determine whether (c + 5) is a factor of
(c4 + 7c3 + 6c2 – 18c + 10).
A. The remainder is 0 and, therefore, (c + 5) is a factor of (c4 + 7c3 + 6c2 – 18c + 10).
B. The remainder is 0 and, therefore, (c + 5) isn’t a factor of (c4 + 7c3 + 6c2 – 18c + 10).
C. The remainder isn’t 0 and, therefore, (c + 5) is a factor of (c4 + 7c3 + 6c2 – 18c + 10).
D. The remainder isn’t 0 and, therefore, (c + 5) isn’t a factor of (c4 + 7c3 + 6c2 – 18c + 10).
