How do I simplify an expresion with sqrt(-1) in the numerator and (4-3i)-(2+5i), I just want to know how to be able to do it

random231 (random231):

just add or subtract the common terms and keep them separate

OpenStudy (anonymous):

But how do you get rid of the square root in the numerator?

random231 (random231):

do u have anything in the denominator?

OpenStudy (anonymous):

(4-3i)-(2+5i) is in the denominator, does that simplify to 2+2i?

random231 (random231):

yeah

random231 (random231):

then multiply 2-2i both in numerator and denominator that will help u get rid of i in numerator but will add i in denominator
