Jamal is doing electronics engineering research and determines the result of his analysis can be expressed in terms of complex numbers. his result is (8-4i)(3i+2) - (5-i) jamal simplified this expression but doesn’t trust his result. will you him by simplifying this complex expression?

a: explain in your own words the value of “i” and the value of “i^2” (short answers )

b: copy the problem carefully and show all the steps needed to arrive at the final simplified answer. you must show all your work for full credit.

c: write your final, simplified expression in standard complex number form for jamal.
