Simplify the expression. (3 i) - (2 - 2i)
a. 1 3i
b. 5 - i
c. 4i
d. -1 - 3i

Option a. 1 3i

Step-by-step explanation:

We have to simplify the expression ( 3 + i ) - ( 2 - 2i)

To solve this expression we will open the parenthesis first.

Since negative sign is given outside the parenthesis so negative sign will change all the signs inside the parenthesis when opened.

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

Now we solve the like terms. If they are of same sign like terms will add and if they are of opposite sign they will get subtracted.

so, 3 + i - 2 + 2i = ( 3i + 1 )

Option a. 1 3i is the answer.

chad should not have included the values (1, 2) and (3, 6) because that would mean he only had half a healing card.
