Step-by-Step Solution

To solve this problem, we'll follow these steps:

  • Step 1: Solve the polynomial equation x4=0 x^4 = 0 .
  • Step 2: Verify the solution against the absolute value equation x+2=x2 |x+2| = |x-2| .
  • Step 3: Ensure the solution matches a provided choice, if necessary.

Now, let's work through each step:

Step 1: Solving x4=0 x^4 = 0 yields x=0 x = 0 , as any non-zero values to the power of 4 would not equal zero.

Step 2: Substituting x=0 x = 0 into the absolute value equation:

0+2=02 |0+2| = |0-2|

2=2 |2| = |-2|

2=2 2 = 2 , thus the condition is satisfied.

Step 3: Compare with provided answer choices. Since the correct choice must satisfy both equations, x=0 x = 0 is consistent with option (1).

Therefore, the solution to the problem is x=0 x = 0 .

Answer

x=0 x=0
