Question

how to simplify (2 + 3i)(3 + i)​

Answer 1

Answer:

Step-by-step explanation:

Answer:

(-5/13)+i(12/13)

Step-by-step explanation:

(2+3i)/(2-3i) let's multiply and divided by

2+3i

(2+3i)(2+3i)/(2-3i)(2+3i)

=4-9+121/2^2-(31)^2. where I used (a-b) (a+b)=a^2-b^2

=-5+121/4+9

=(-5+12i)/13

=(-5/13)+i(12/13).
