Question

simplify.
(4 - 4i) + (8 + 7i)
write your answer in the form a + bi.

Explanation:

Step1: Combine real parts

Add the real parts \(4\) and \(8\): \(4 + 8 = 12\)

Step2: Combine imaginary parts

Add the imaginary parts \(-4i\) and \(7i\): \(-4i + 7i = 3i\)

Step3: Form the result

Combine the real and imaginary parts to get \(12 + 3i\)

Answer:

\(12 + 3i\)
