Algebra-2

To solve the equation , we need to consider two cases because of the absolute value:

Case 1: When , i.e.,  → 

In this case, the absolute value is equal to . So our equation becomes:

Now we need to check if this solution is valid for the original equation. We substitute the values of back into the original equation.
Left side:
Right side:

Since the left side equals the right side, is a valid solution.

Case 2: When , i.e., →
