Which of the following values of x do not satisfy the inequality x2 - 3x + 2 > 0 at all ?	Choose the correct choice from the following answers:
A) 1 ≤ x ≤2 B) -1 ≥ x ≥ -2 C) 0 ≤ x ≤ 2 D) 0 ≥ x ≥ -2 E) None of these
Explanation :   On solving x2 - 3x + 2 &gt; 0 , we get ( x - 1 )( x - 2 ) &gt; 0.   That is the roots are x = 1 or x = 2.   The equation assumes a positive value for all values which belong to the interval less than 1 and greater than 2   For x = 1 and x = 2, it becomes zero and for any value of x between 1 and 2 it becomes negative.   1 ≤ x ≤2nswer : 1 ≤ x ≤2
