8-113.

The graph of is shown at right. Homework Help ✎

  1. Use the graph to determine one solution to , then use the Factor Theorem to write a factor of . Read about the Factor Theorem in the Math Notes box in this lesson.

    Where does the graph cross the -axis? What is the associated factor?

  2. Determine all the factors and roots of , including any with complex coefficients.

    Divide the factor from part (a) into to obtain a quadratic factor.
    Then use the Quadratic Formula to find the roots.
    Use the roots write the associated factors.
