\[\frac{ -5+i }{ 2i }\]
yes
ok, extend fraction by i. use this rule: i*i=-1 (definition) -5i -1 ------ 2*-1
okay so -5(-1)-1 --------- -2 right? or is that an answer that you wrote
original equation: -5 + i ----- 2 i extend numerator and denominator by i: i (-5 + i) --------- i (2 i) calculate: -5 i + i*i --------- 2 i * i use the rule i*i = -1: -5i +(-1) -------- 2 (-1)
