(4-5i) -(6-i) = 4-5i -6+i = -2-4i (4−5i)−(6−i)=4−5i−6+i=−2−4i
Explanation:
To add or subtract complex numbers we just add or subtract the real and imaginary components separately, thus:
(4-5i) -(6-i) = 4-5i -6+i (4−5i)−(6−i)=4−5i−6+i
\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ = 4-6-5i +i
\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ = -2-4i
