I guess the answer is to find the minimum value of the function f(x) = (x^2+9)(2x+6)

Just the product (xÂ² + 9)(2x + 6).

You can ALMOST get away with less, but unfortunately, xÂ² + 9 is not factorable. (You'd need xÂ² - 9 = (x + 3)(x - 3) to find any common factors.)

8(x+3)(x^2+9)
Cant do any better than that.
