8-113.

The graph of is shown at right. Homework Help ✎

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.
