to find the difference of these complex numbers. I'm going to start by distributing the negative. So we have two minus eight. I minus two minus eight. I Now we can combine the rial parts to minus two and that gives us zero, and we can combine the imaginary parts. Negative eight i and negative eight I and that gives us negative 16 I. So writing it in a plus B I form is zero minus 16. I
