The correct Answer is:
To solve the equation \( |z^2 - 9| + |z^2| = 41 \) for the complex number \( z \), we will follow these steps: ### Step 1: Rewrite the equation We start with the equation: \[ |z^2 - 9| + |z^2| = 41 \] ### Step 2: Use the triangle inequality We can apply the triangle inequality: \[ |z^2 - 9| + |z^2| \geq |(z^2 - 9) + z^2| = |2z^2 - 9| \] This means: \[ |2z^2 - 9| \leq 41 \] ### Step 3: Analyze the expression From the triangle inequality, we can derive: \[ -41 \leq 2z^2 - 9 \leq 41 \] This implies: \[ -41 + 9 \leq 2z^2 \leq 41 + 9 \] \[ -32 \leq 2z^2 \leq 50 \] ### Step 4: Divide by 2 Dividing the entire inequality by 2 gives: \[ -16 \leq z^2 \leq 25 \] ### Step 5: Consider the modulus Since \( z^2 \) is a complex number, we can consider the modulus: \[ |z^2| \leq 25 \] This means: \[ |z|^2 \leq 25 \implies |z| \leq 5 \] ### Step 6: Maximum value of \( |z| \) The maximum value of \( |z| \) is therefore: \[ |z| \leq 5 \] ### Step 7: Verify the conditions We also need to check if the equality can hold. The equality \( |z^2 - 9| + |z^2| = 41 \) can be satisfied under certain conditions, but we have established the bounds for \( |z| \). ### Conclusion The true statements among the options provided are: 1. \( |z| \leq 5 \) 2. The equation can hold under certain conditions.
