Daine simplified the expression below.
8(1 + 2i) β (7 β 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 β 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.
