From the graph, what number appears to be an integer solution to the equation?

Verify that your answer to part (a) is a solution.

Substitute your answer from part (a) into the original equation.

Since you know a solution to the equation, what is the factor associated with this solution?

Use polynomial division to determine the other factor.

Divide

byusing an area model. Use your new factor to complete the following equation.

(other factor) The “other factor” leads to two other solutions to the equation. What are the two other solutions? State all three solutions to the original equation.

Use the Quadratic Formula on the "other factor".
