Question 1057507
There is nothing to "solve" here, but the expression can be simplified:


-4 - (1 + i) - (5 + 9i)


-4 - 1 - i - 5 - 9i


-4 - 1 - 5 - i - 9i


-10 - 10i


<strong>-10(1 + i)</strong>


Note that I have assumed that "I" and "i" represent the same variable 
(usually meant to indicate the root of -1).
