Carlos is always playing games with his graphing calculator, but now his calculator has contracted a virus. The , so he graphs

*and sees the graph below in the standard window.*

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

Check your answer from part (a) in the equation.

Since

is a solution to the equation, what is the factor associated with this solution?Use polynomial division to find the other factor.

Divide

byusing a generic rectangle.Use your new factor to complete this equation:

The “other factor” leads to two other solutions to the equation. Find these two new solutions and give all three solutions to the original equation.

Try using the quadratic formula.
