Math Problem Statement

solve this. |x-2|-4>2

Solution

To solve the inequality x24>2|x - 2| - 4 > 2, let's go through it step-by-step:

  1. Isolate the absolute value: x2>6|x - 2| > 6

  2. Rewrite the inequality without the absolute value: When solving x2>6|x - 2| > 6, we split it into two cases:

    • Case 1: x2>6x - 2 > 6 x>8x > 8

    • Case 2: x2<6x - 2 < -6 x<4x < -4

  3. Combine the solutions: The solution to x24>2|x - 2| - 4 > 2 is: x>8orx<4x > 8 \quad \text{or} \quad x < -4

So, the solution in interval notation is: (,4)(8,)(-\infty, -4) \cup (8, \infty)
