What is the solution set to the inequality open paren 4 x minus 3 close paren times open paren 2 x minus 1 close paren is greater than or equal to 0 ?

The factors are zero at x = 3/4 and x = 1/2. Since the product is nonnegative when both factors have the same sign, the solution is x ≤ 1/2 or x ≥ 3/4, including the zeros because the inequality allows equality. This matches choice B: x is less than or equal to 1/2 or greater than or equal to 3/4.
