Simplify the expression below as Mich as possible

(6+3i) + (8+4i) - (1+4i)

A. 13+11i

B. 15+3i

C. 13+3i

D. 15+11i

Answer: c. 13 + 3i

(6 + 3i) + (8 + 4i) - (1 + 4i)

(6 + 3i) + (8 + 4i)

(since you're adding, there's no need to change signs, just add like terms)

6 + 8 = 14 3i + 4i = 7i

7i + 14

(7i + 14) - (1 + 4i)

(since you're subtracting, you have to change signs for the second binomial and then add like terms)

7i + 14 - 1 - 4i

7i - 4i = 3i 14 - 1 = 13

3i + 13
