Question

The imaginary number i is equal to

−1
, which expression is equivalent to −(4 + 3i) + (2 + 2i)?
A) 2 + 2i
B) 2 − i
C) −2 + i
D) −2 − i

Answer 1

D

Explanation:

An equivalent expression is an expression which is equal to −(4 + 3i) + (2 + 2i). You can expand or simplify an expression to make an equivalent expression. Combine like terms - constants with constants and imaginary with imaginary - to simplify.

−(4 + 3i) + (2 + 2i) = -4 + 2 -3i + 2i = -2 - i
