Multiply the complex numbers: 1: (1 - 4i)(3 - 3i)
2: (2 + i)(3 + 3i)
3: (-7i)(7i)(-7 - 8i)

Step 1

Step 2: Simplify the powers of i, specifically remember that i2 = –1.

Step 2

Step 3: Combine like terms, that is, combine real numbers with real numbers and imaginary numbers with imaginary numbers.

Step 3

Step-by-step explanation:

1:-9 - 15 i

2: 12 + 6 i

3: -343 - 392 i

answer: i believe the answer is e

my guess would be b and d, but i didn’t actually get out the pen and paper. lol
