For any x ∈ R +, the inequality ax ^ 2-2ax-3

When a = 0, the inequality becomes - 3

When x takes which integers, the inequality x + 22x-9 holds at the same time?

x+22x-9
3x-6＞2x-9;
x＞-3;
∴-3＜x＜1;
The integer solution is - 2, - 1,0,

What is the solution set of inequality 3 ＜| 5-2x | ≤ 9?

Equivalent to
three

Solving inequality: 3 ≤ L 5-2xl

3≤|5-2X|＜9
When 5-2x > = 0
x

If x = 3 is the solution of equation 2x-a + 2 = x + 1, then the solution set of inequality a + x2 < 3 is______ ．

∵ x = 3 is the solution of the equation 2x-a + 2 = x + 1, ∵ a = 4. Substituting a = 4 into the inequality a + x2 < 3, we get 4 + x < 6, x < 2

Given that x = 2 is the solution of the equation (2x-m) / 3-2 = x + m, find the solution of the inequality (1-m / 3) x less than (1-m) / 2

Take x = 2 into the equation (2x-m) / 3-2 = x + m to get m = - 2. Take M = - 2 into the inequality (1-m / 3) x is less than (1-m) / 2 to get x < 3 / 2

If the solution of equation (M + 2) x = 5 of X is x = - 5, then the solution set of inequality (M + 2) x > 3 is

Because the solution of (M + 2) x = 5 is x = - 5,
So - 5 (M + 2) = 5,
m+2=-1
m=-3.
So (M + 2) x > 3 is (- 3 + 2) x > 3,
That is - x > 3,
So x

Given that the solution of equation (M + 2) x = 4 is x = 2, please find the solution set of inequality (m-2) x > 3

If the solution of (M + 2) x = 4 is x = 2, then (M + 2) * 2 = 4, the solution is m = 0
The inequality (m-2) x > 3 is 0 > 3, which is not tenable
Therefore, the inequality has no solution, that is, the solution set is empty
