simplify the expression to a + bi form:
(8 - 6i) - (4 - 4i)

Explanation:

Step1: Distribute the negative sign

We have \((8 - 6i)-(4 - 4i)=8 - 6i - 4 + 4i\)

Step2: Combine like terms (real parts and imaginary parts separately)

For the real parts: \(8-4 = 4\)
For the imaginary parts: \(-6i + 4i=-2i\)
So combining these, we get \(4-2i\)

Answer:

\(4 - 2i\)
