I'm having a hard time with this problem. Add: -6+i ----- -7-5i

OpenStudy (anonymous):

excuse me, Perform the indicated operation. Not add.

OpenStudy (anonymous):

just multiply the numerator/denominator by the conjugate of the denominator which is (-7 + 5i)

OpenStudy (anonymous):

I'm getting some funky numbers for the numerator. If i'm not mistaken the denominator is 2?
