Question

Simplify the expression (3+i) + (5-2i) and write the result in the form a + bi

Answer 1

remove unnecessary parenthesis, and combine like terms
(3+i) +  (5-2i)

3+i   +  5-2i

8+i



you added 3+5 which is 5 and i-2i which is "i"

hope this helps.

Answer 2

Answer: 8-i

Step-by-step explanation: when working with imaginary numbers in the form "a+bi" we can add together the similar terms (the real numbers together and the imaginary numbers also together respectively). So we can simplify the given expression as follows:

(3+i)+(5-2i)=

3+5+i-2i=

8-i
