@Nnesha

Nnesha:

distribute 2nd parentheses by -1 and then combine like terms add the coefficient with the variable i

zarkam21:

@satellite73 can you help please

zarkam21:

@satellite73 oh lol I just opened peer answer and saw that you replied

zarkam21:

?

satellite73:

i am here

satellite73:

\[(3-8i)-(6+2i)=3-8i-6-2i=-3-10i\]

zarkam21:

Hi =)

zarkam21:

OKay so would that be for step 1?

satellite73:

distribute the minus sign

satellite73:

it would be the same fo r\[(3-8x)-(6+2x)\]

satellite73:

just with an \(i\) instead of an \(x\) like combining like terms remove the parentheses using the distributive property first, then combine like terms

zarkam21:

Okay so would all of this be step 1?

satellite73:

\[(3-8i)-(6+2i)\] step one, distribute the minus sign \[3-8i-6-2i\]

zarkam21:

Play and then step 2

zarkam21:

Okay**

satellite73:

maybe you can arrange the like terms next to each other, not sure if that is a step or not \[3-6-8i-2i\]

satellite73:

or just combine the like terms \[-3-10i\]

satellite73:

ok now i see it says "rewrite as an addition problem" we can do that too

satellite73:

\[(3-8i)-(6+2i)=(3-8i)+(-6-2i)\]

satellite73:

it is silly, but you can write it like that then second step is still to combine like terms, and you still get \[-3-10i\]

zarkam21:

Okay so step one is (3-8i)-(6+2i)=(3-8i)+(-6-2i)

zarkam21:

and then step two -3-10i
