Question

simplify.
$-(-6 - 7i) - (6 - 2i)$
write your answer in the form $a + bi$.

Explanation:

Step1: Distribute the negative signs

$-(-6 - 7i) = 6 + 7i$; $-(6 - 2i) = -6 + 2i$

Step2: Combine real parts

$6 + (-6) = 0$

Step3: Combine imaginary parts

$7i + 2i = 9i$

Step4: Sum real and imaginary results

$0 + 9i$

Answer:

$0 + 9i$
