How do i solve (14-5i) + (-8+19i)

Multiply them across. Like this

14*-8=-112

14*19i=266i

-5i*-8=40i

-5i*19i=-95i^2

-112+266i+40i-95i^2

First before combining like terms, you first turn - 95i^2 to 95 because i^2 is - 1. Then you multiply - 1, which was i^2, with - 95, which will give you 95.

So now you - 112+266i+40i+95

Combine like terms which will be: - 112+95 = - 17

266i+40i = 306i

So now your answer will be - 17+306i
