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 isn't 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 is 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) Question solved general 11 months ago 8882
