Answer 1

Remove the parentheses around the expression 3+6i.

3+6i−(8−5i)


Multiply −1 by each term inside the parentheses (8−5i).

3+6i−(8)−(−5i)


Multiply −1 by the 8 inside the parentheses.

3+6i−8−(−5i)


Multiply −1 by the −5i inside the parentheses.

3+6i−8−1⋅−5i


Multiply −1 by −5i to get 5i.

3+6i−8+5i
3+6i−8+5i
Subtract 8 from 3 to get −5.
−5+6i+5i
Since 6i and 5i are like terms, add 5i to 6i to get 11i.
−5+11i
