can you help @Nnesha and @sohailiftikhar

first of all distribute 2nd parentheses by negative one

|dw:1438709754483:dw|
-1(6-10i) distribute

-6+10i

it's 3+5i

yep right now combine *like terms \[\huge\rm -2i+9-3i -6+10i\]

but if i was to distribute to the first part both numbers would be imaginary

3+5i

do you mean first parentheses ?

yeah

there is a plus sign so you don't have to distribute
just remove the parentheses

\[-2i-3i+10i+9-6=3i+5\]

you just have to add or subtract like numbers only

|dw:1438709987964:dw| was how they showed me

that was the example they gave me

ok Nnesha you here

same like last one so what would be the first step ?

okay so this one i would combine right ?

nope that's 2nd step

\[ \huge\rm (21 − 4i) \color{ReD}{−} (16 + 7i) + 28i \] there is a negative sign so.?

lol it's not a level of child Nnesha

what do you mean by that ?

i would add a 1?

just combine the terms and get answer what is that mean by 1st step and 2nd ?

there are steps to solve any math questions

yes but we have to see where we need then or where we can directly

21- 16 would be 5 and it would be subtraction after that right ?

so if you have given with a lengthy Question and then you will still use every basic step huh ?

if you start with combining like terms you would get wrong answer

what if you are solving multiple choices and you have short time to do them huh ?

the last part would be 17 but is it negative ?

you can't get wright answer without doing first step.

not for this Question

right*

at this point we should focus on this question.

agreed ^

so it would be 5+17I right?

yes so it can solve by just adding terms

ok don't mind this bye

thanks again guys you've been a really big help!!!

no problem buddy

yes but we done this in our mind not on page because it's simple in this case
