To solve this problem, we'll follow these steps:
Now, let's work through each step:
Step 1: The given equation is . Let's expand both sides:
- Left side: based on the difference of squares formula.
- Right side: using the square of a sum formula.
Step 2: Setting the expanded forms equal gives us:
.
Step 3: Simplify and solve the equation:
- Subtract from both sides: .
- Add to both sides: .
- Factor the right-hand side: .
This gives us two possible conditions:
1) , which implies .
2) , which implies .
Since satisfies the equation for any if is not zero, and when , the equation simplifies to , both conditions are valid.
Therefore, the solutions are or .
In conclusion, the answer is: or .
or
