Simplify the expression. **Expression below**

OpenStudy (anonymous):

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

OpenStudy (anonymous):

separate it into 2 separate fractions and see what you see

OpenStudy (anonymous):

how

OpenStudy (anonymous):

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

OpenStudy (anonymous):

I dont see what to do

OpenStudy (anonymous):

the i's will cancel eachother out.

OpenStudy (anonymous):

in which places, how would it look after that

OpenStudy (anonymous):

times by 2i over 2i and remeber i times i is 1

OpenStudy (anonymous):

im sorry, but I am soo confused.

OpenStudy (anonymous):

okay here it is:

OpenStudy (anonymous):

\[\frac{ -5+i }{ 2i } \times \frac{ 2i }{ 2i } = \frac{ 2i(-5+i) }{ 2i \times 2i }\]

OpenStudy (anonymous):

so that is

OpenStudy (anonymous):

\[\frac{ -10i -2 }{ -4 } \]

OpenStudy (anonymous):

or simplified to \[\frac{ -5i-1 }{ -2 } = \frac{ 5i+1 }{ 2 }\]

OpenStudy (anonymous):

and that is the lowest it simplifies to?

OpenStudy (anonymous):

yes
