Consider the polynomial function () = −4" − 4! + 4.
a. Confirm that = () is not factorable.
b. The student Dazzlegleam thinks you can use the Quadratic Formula to solve for the zeros; however, the given function is not a quadratic. BUT...... there is a way to modify the Quadratic Formula to work here that will give you the FOUR zeros you know you need. What is it? Why does it work?
c. Use the Quadratic Formula to find the zeros
d. Wait – I thought Unit 4 was about quadratics! Explain how this question relates to Quadratics.
