Question

which two complex numbers when subtracted from each other will give you another complex number from the table a) 7 - 3i b) -5 - 8i c) 12 + i d) -4 + 9i e) 6 - 6i f) -9 + 15i g) 1 + 10i h) 11 - 12i

Answer 1

A − D

Explanation:

The difference of A and D equals the complex number in row H in the table (6 − 10i):

A − D = -3 − 4i − (-9 + 6i)

= -3 − 4i + 9 − 6i

= -3 + 9 − 4i − 6i

= (-3 + 9) + (-4 − 6)i

= 6 − 10i

Answer 2

(7-3i) - (-4+9i)
