OpenStudy (debbieg):

rationalize the denominator by multiplying the whole thing by CC/CC where CC=the complex conjugate of the denominator.

OpenStudy (debbieg):

So you need: \[\large \left(\frac{ 2 }{ 2+5i }\right)\cdot\left(\frac{ 2-5i }{ 2-5i }\right)\]

OpenStudy (debbieg):

Well good, glad you were able to figure it out. And if it's an online quiz or assessment, it should be your own work, anyway. :)
