Answer
(-10 + 10i) + (10 - 5i) = 0 + 5i
a = 0
b = 5
Explanation
We are asked to simplify the expression given in the form of a + bi
(-10 + 10i) + (10 - 5i)
The key is to group and simplify the real parts together and then the complex parts together too.
(-10 + 10i) + (10 - 5i)
= -10 + 10i + 10 - 5i
= -10 + 10 + 10i - 5i
= 0 + 5i
Hope this Helps!!!
