Question: Perform indicated operations and write the answer in the $a + bi$ form. $(4 + i) - (2 - 3i) - (3 - 2i)$
1. **State the problem:** We need to simplify the expression $(4 + i) - (2 - 3i) - (3 - 2i)$ and write the result in the form $a + bi$. 2. **Recall the rule for subtraction of complex numbers:** Subtract the real parts and the imaginary parts separately. 3. **Rewrite the expression by distributing the minus signs:** $= (4 + i) - 2 + 3i - 3 + 2i$ 4. **Group real and imaginary parts:** Real parts: $4 - 2 - 3$ Imaginary parts: $i + 3i + 2i$ 5. **Calculate the sums:** Real: $4 - 2 - 3 = (4 - 2) - 3 = 2 - 3 = -1$ Imaginary: $1i + 3i + 2i = 6i$ 6. **Write the final answer:** $$-1 + 6i$$ Therefore, the answer is $-1 + 6i$. 7. **Match with options:** Option (a) is $-1 + 6i$. **Final answer:** (a) $-1 + 6i$
