The absolute value of X-2 plus 2x + 1 = 8

The absolute value of X-2 plus 2x + 1 = 8

There are four situations
X-2 + 2x + 1 = 8, so there are four results after simplification
As follows:
The first is that both are positive numbers
X-2 + 2x + 1 = 8 solution x = 3
The second is that both are negative
- x + 2-2x-1 = 8 solution x = - 3
The third is one positive and one negative
X-2-2x-1 = 8 solution x = - 11
The fourth is one negative and one positive
- x + 2 + 2x + 1 = 8, solution x = 5
