Answer

(-10 + 10i) + (10 - 5i) = 0 + 5i

a = 0

b = 5

Step-by-step 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!!!
