Based on the zero product property, if the product of two factors equals zero, at least one of the factors must equal zero. Therefore, for the quadratic equation \((3x + 4)(x - 2) = 0\), the correct statement is:
At least one of the factors (3x + 4) or (x - 2) must equal 0 for the entire function to equal 0.
So, the answer is the last statement provided.
