The graph of
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?
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.
