Imaginary and Complex Numbers Adding Subtracting

What is the simplifies form of (11 - 7i) - (-3 + 12i) (remember to distribute the negative)

• 8 - 19i

• 8 + 5i

• 13- 19i

• 14 -19i

Answer explanation

To simplify (11 - 7i) - (-3 + 12i), distribute the negative: (11 - 7i) + (3 - 12i). Combine real parts: 11 + 3 = 14, and imaginary parts: -7 - 12 = -19i. Thus, the result is 14 - 19i.
