Assume the graph of a 4th-degree polynomial crosses the x-axis at exactly -2, 2, and 5. Let k be the leading coefficient with k > 0.
Give a possible formula for this 4th-degree polynomial.
Edit: Does this homework count towards your grade? If so it's against forum rules for me to help. Nevertheless, since we've already gone over the answer, I'm still curious why the answer would be rejected by the checker.
