Question

|a+x|/2 − |a−x|/2 , if a=−2; x=−6

PLZ HELP!!!

Answer 1

2

Explanation:

So you're dealing with absolute value which means that whatever is inside these symbols | | will be positive after all the calculations inside are done.

Plug in your values

|(-2) + (-6)|/2

-2 - 6 = -8

absolute value of -8 is 8

8/2 = 4

First part is 4

|(-2) - (-6)|/2

-2 + 6 = 4

4/2 = 2

Second part is 2

Put the two values back into your original equation

4-2 = 2

Answer 2
