Questions and Answers

What is the remainder when a polynomial p(x) is divided by cx - d?

  • p(-d/c)
  • p(cx)
  • p(d/c) (correct)
  • p(c/d)
  • Given a polynomial p(x) and a divisor cx - d, what is the general form of the polynomial division?

  • p(x) = (cx - d) · R + Q(x)
  • p(x) = (cx + d) · Q(x) - R
  • p(x) = (cx + d) · R - Q(x)
  • p(x) = (cx - d) · Q(x) + R (correct)
  • What is the degree of the quotient Q(x) when dividing a polynomial p(x) by a linear polynomial cx - d?

  • One degree less than p(x) (correct)
  • One degree more than p(x)
  • Two degrees less than p(x)
  • The same degree as p(x)
