Answer:
a = 13
b = 0
Step-by-step explanation:
Conjugate of -3 + 2i is -3 - 2i
(-3 + 2i) (-3 - 2i)
We need to expand:
9 + 6i + -6i + -4i^2
-4i^2 =(-4)(-1) = 4
9 + 4 = 13
a = 13
b = 0
Opposite sides are parallel i.e W || Y & X || Z
Eight point one, five, seven.
Or you could write it like: 8 plus point one, five, seven :)
