Answer:
{x| x≤ 1/2 or x ≥ 3/4}
Step-by-step explanation:
The values of x that make the factors zero are 3/4 and 1/2. The product of these factors will be positive when both factors are negative (for x < 1/2) or when both factors are positive (x > 3/4). The matching answer selection is the third one.
