Explanation:
Complex numbers can be added like anything else. This expression is no different than
(−3−3x)−(5−5x)
The only potential stumbling blocks are positives/negatives and combining like terms.
First, distribute the negative sign into the second pair of parentheses.
(−3−3i)+(−5+5i)
From here, add the constants and imaginary parts separately.
(−3−5)+(−3i+5i)
−8+2i
