Subtract: (2 - 3i) - (4 + 3i).

Question

[Write your answer as a+bi. Type the real number, then a plus or minus sign, then the imaginary number, then the lowercase i. Do NOT type any spaces or parentheses.]

Answer 1

Essentially you can treat the x like a variable. Solve it just like it is an x. Combine like terms. so,

2-4 = -2 that is the real part and -3i - 3i = -6i

put them together and you get -2 - 6i
