Evaluate the expression (-2 - 4i) - (-2 + 6i) and write the result in the form a + bi.
The real number a equals
The real number b equals

Answer

Evaluate the expression: (-2 - 4i) - (-2 + 6i)

First, distribute the negative sign:

= (-2 - 4i) + 2 - 6i

Combine like terms:

Real part: -2 + 2 = 0

Imaginary part: -4i - 6i = -10i

So, the result is 0 - 10i.

  1. The real number a equals 0.
  2. The real number b equals -10.
