Simplify the expression

OpenStudy (anonymous):

\[\frac{ -5+i }{ 2i}\]

jimthompson5910 (jim_thompson5910):

Multiply top and bottom by \(\Large i\) to rationalize the denominator

jimthompson5910 (jim_thompson5910):

keep in mind that \[\Large i^2 = -1\]

OpenStudy (anonymous):

Okay so I will have \[\frac{ -5+i }{ 2i} \times \frac{ i }{ i }\] \[\frac{ -5 - 1 }{ 2(-1) }?\]

@jim_thompson5910 is that right?
