Find the missing term.

if y = 1 + i, then y^3 − 3y^2 + − 1 = -i
what would the "? " equal to.

a) -3y
b) -3y + 1
c) 3y
d) 3i

C

Step-by-step explanation:

Simplify everything to get :

-3 - 4i + (?) = -i

From this we know that we need 3i + 3 to get -i.

3y = 3(1 + i)

3y = 3 + 3i

So the answer is C.
