B/a = (3 - 2i)/(2 + i)
To divide complex numbers, you multiply the numerator and denominator by the complex conjugate of the denominator.
The complex conjugate is 2 - i. ** Remember i^2 = -1 **a + bi
( 3 - 2i) ( 2 - i)
------------------- Foil numerator and denominator.
(2 + i) ( 2 - i)
6 - 3i - 4i + 2i^2 6 - 7i - 2 4 - 7i 4 - 7i
--------------------- ----------- ------- OR --- -----
4 - i^2 4 + 1 5 5 5
The answer can be written either way. If they specify real part and imaginary part, the second option is correct.
It is a linear because it’s a constant rate of change
