What's on the worksheet

  1. Give the degree of each polynomial and list every root with its multiplicity.
    (x^2 + 6x + 9)(x^2 + 6x + 10)(2x + 1)^2(x^2 - 2x + 5)x^5 - 8x^2
  2. Use the degree 5 graph to find all roots, including non-real ones.
  3. Factor a degree 5 polynomial by grouping and list every root.
  4. Use a given complex root of a quartic with real coefficients to find all four roots.
  5. Decide true or false for each statement about roots, with a reason or example.
