HELP ASAP I NEED IT BADDDD !!
murzikaleks [220]

Answer:

The correct complex numbers would be, -2 - 4i and 2 + 2i

(−2 − 4i) − (2 + 2i) = -4 - 6i

Step-by-step explanation:

(−2 − 4i) − (2 + 2i)

Subtract 2 + 2i from −2 − 4i by subtracting corresponding real and imaginary parts.

−2 − 2 + (−4 − 2)i

Subtract 2 from −2. Subtract 2 from −4.

-4 - 6i

So, the correct complex numbers would be, -2 - 4i and 2 + 2i
