For what values of x does the graph of h have a point of inflection? I am stuck on what to do after the second derivative which I found was: 6x^1+60x^2. I tried to factor it which gave me: 6(10x^2+x), but then I don't now how else to factor it until it becomes separated by two parentheses like my other previous problems. Could you help me out with the next steps?

There is a point of inflection at x = -3 (the first derivative has a turning point there), but not at x = 0 (the first derivative doesn't have a turning point there).
