Daine simplified the expression below.
8(1 + 2i)-(7 –3i) = 1 + 5i
What mistake did Daine make?
He did not apply the distributive property correctly for 8(1 + 2i).
He did not distribute the subtraction sign correctly for 7 - 3i .
He added the real number and coefficient of i in 8(1 + 2i).
He multiplied the two complex numbers when he should have subtracted.
