earn the medals

OpenStudy (anonymous):

awwww

OpenStudy (anonymous):

Sorry.

OpenStudy (anonymous):

i have one more problem i have been struggling with

OpenStudy (anonymous):

9+12i/-4i

OpenStudy (anonymous):

multiply numerator n denominator with 4i

OpenStudy (anonymous):

i got 36i+48i/-16i^2

OpenStudy (anonymous):

good, now simplify it, i^2 =-1, keep this in mind

OpenStudy (anonymous):

n its 48i^2

OpenStudy (anonymous):

so i got 36i-48/16

OpenStudy (anonymous):

now draw the factor out that is common in numerator

OpenStudy (anonymous):

the factor is 4

OpenStudy (anonymous):

its 6

OpenStudy (anonymous):

how do i type that out on my homework site

OpenStudy (anonymous):

it does not want it in that form

OpenStudy (anonymous):

in which form u want it?

OpenStudy (anonymous):

it wants it in a+bi

OpenStudy (anonymous):

36/16i-48/16 =9/4i -3

OpenStudy (anonymous):

36/16i+48/16 =9/4i +3

OpenStudy (anonymous):
