simplify and write answer in standard form (a+bi) 3-(-2+3i)+(-5+i)

OpenStudy (freckles):

just combine like terms

OpenStudy (freckles):

you have 3+2-3i-5+i

OpenStudy (freckles):

So you know what 3+2-5 is and you know what -3i+i is

OpenStudy (anonymous):

so -2i?

OpenStudy (freckles):

yes because 3+2-5 is definitely 0 and -3i+i=-2i and 0-2i is still -2i

OpenStudy (anonymous):

but the answer key my teacher gave us said the answer was 0? I am confused

OpenStudy (anonymous):

your teacher made a boo boo

OpenStudy (freckles):

or the wrong problem is posted

OpenStudy (anonymous):

Oh, she probably made an mistake. Thanks for the help :)
