The graph of
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?
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.
