Please help me with these Solving and Graphing Polynomials problems for my notes if you can.

1. One factor of f(x) = x^3 - 3x^2 - 28x + 60 is (x - 6). What are the zeros of the function?

2. What is the average rate of change from x = 0 to x = 2 for f(x) = 3x^3 - 9x^2 + 6?

Please show and explain all your steps. Thank you for your help.
