The graph of is shown at right

  1. Use the graph to find one solution to, then use the Factor Theorem to find 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 real and complex zeros of

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

A curved continuous graph, with arrows at both ends, that rises from the bottom left, to a point in the third quadrant, falls to approximately the point, (0, comma negative 26), then rises, crossing the, x axis, at 2.
