Answer:
Step-by-step explanation:
To simplify or to write in the form a+bi, you will need multiply the top and bottom by the bottom's conjugate like so:
Keep in mind when multiplying conjugates you only have to multiply first and last.
That is the product of (a+b) and (a-b) is (a+b)(a-b)=a^2-b^2.
(a+b) and (a-b) are conjugates
Let's multiply now:
i^2=-1
