Simplify the expression.
( -5 + i ) * i -5i + i^2 -5i - 1 - (5i + 1) 5i + 1
_________ = _______ = ________ = _______ = _______
2i * i 2i^2 -2 -2 2
Multiply top and bottom by -2i
(-5+ i )/ 2i * -2i/-2i = -10i - 2i^2 / -4i^2 = ( 2 - 10 i ) / 4 = ( 1-5i) / 2
(NOTE: You COULD have just multiplied top and bottom by -i to get same result )
