Question

5i - (2-i)

I know the answer is -2+6i I need help with how I would start the work

Answer 1

By start the work do you mean show it? Like show the steps?

Answer 2

Yes

Answer 3

Ok so lets remove the parentheses first? What do we get?

Answer 4

5i - 2 - i

Answer 5

Not exactly
this equation is the same as 5i+-(2-i)
and -(2-i) is -2+i
So we would get
5i-2+i

Answer 6

Then we would move the -2 to where in this equation? before the 5i or after the i

Answer 7

Before

Answer 8

Yes!
so we have
-2+5i+i

Answer 9

Then you would just combine the i
