If f(x) = 2x²  8x + 9, which statement regarding the vertex form of f(x) is true?
A.) In vertex form, f(x) = 2(x  2)² + 1 and therefore has a minimum value of 1. B.) In vertex form, f(x) = 2(x  2)² + 1 and therefore has a minimum value of 2. C.) In vertex form, f(x) = 2(x  2)² + 4.5 and therefore has a minimum value of 4.5. D.) In vertex form, f(x) = 2(x  2)² + 4.5 and therefore has a minimum value of 2.
The expression 3x²  33x  180 can be factored into the form a(x + b)(x + c), where a, b, and c are constants, to reveal the zeros of the function defined by the expression. What are the zeros of the function defined by 3x²  33x  180?
