    2x² - 5x - 8

    Step-by-step explanation:

    f (x) + g (x)

    = (2x²+3x-4) + (-8x-4)

    = 2x² - 5x - 8

    2x^2 - 5x - 8

    Step-by-step explanation:

    f (x) = 2x^2+3x-4,

    g (x) = -8x-4,

    f (x) + g (x) = 2x^2+3x-4 + - 8x-4

    Combine like terms

    = 2x^2 + 3x - 8x - 4-4

    =2x^2 - 5x - 8
