OpenStudy (sidsiddhartha):
(7+4i)-(5-6i)=7+4i-5+6i=2+10i=2(1+5i)
OpenStudy (anonymous):
sadly no... your imaginary term is wrong. Remember you are subtracting a negative number, so it becomes positive
OpenStudy (anonymous):
2 + 10i is the right answer
OpenStudy (anonymous):
Oh okay!! So like sid said, it is 2+10i. Got it now!
OpenStudy (sidsiddhartha):
yup
