Carlos is always playing games with his graphing calculator, but now his calculator has contracted a virus. The
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
by using 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.
