    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
