<= .
Move the terms from the right side to the left, changing the signs. You will get an equivalent inequality
<= 0.
Factor the left side:
(2x-1)*(x-2) <= 0.
Divide both sides by 2. You will get an equivalent inequality
(x-1/2)*(x-2) <= 0. (1)
1) If x < then both factors (each factor) in the left side of (1) are/is negative,
So the product is positive.
2) If < x < 2 then the factor (x-1/2) is positive, while the factor (x-2) in the left side of (1) is negative,
so the product is negative.
3) If 2 < x then both factors (each factor) in the left side of (1) are/is positive,
so the product is positive.
Answer. The given inequality has the segment [1/2,2] as the solution set.
Solved.
