1.perform the indicated operation and write the result in the form a+bi -9i(-9i+4)+3(8+8i) a. 12+57i b. 57-60i c. -105-60i d. -57-12i

-9i(-9i+4)+3(8+8i)

Use the distributive property to remove the parenthesis:

-9i * -9i = 81i^2

-9i x 4 = -36i

3x8 = 24

3x8i = 24i

Now you have 81i^2 - 36i + 24 + 24i

i^2 = -1

Now you have 81 x -1 - 36i + 24 + 24i

-81 +24 = -57

-36i +24i = -12i

Final answer = -57 - 12i
