    a) (f+g) (x) = 6x^2 + 6x - 10

    b) (f-g) (x) = 6x^2 - 2x - 4

    Step-by-step explanation:

    a. (f+g) (x) = f (x) + g (x) = (6x^2 + 2x - 7) + (4x - 3)

    (f+g) (x) = 6x^2 + 6x - 10

    __

    b. (f-g) (x) = f (x) - g (x) = (6x^2 + 2x - 7) - (4x - 3)

    (f-g) (x) = 6x^2 + 2x - 7 - 4x + 3

    (f-g) (x) = 6x^2 - 2x - 4
