Answer: -1/2 -2i
Explanation:
Hi, to answer this question we have to simplify the expression:
First, we have to apple distributive property for the (-) sign. It’s like having the number -1 multiplied by the sum.
5/4-(7/4+2i)
5/4 -1(7/4+2i)
5/4 (-1) 7/4 (-1)2i
5/4 -7/4 -2i
Now we add both numbers (with no variable ⇒5/4 + (-7/4) )
-1/2 -2i or
(-1/2)+ (-2)i
