    ( - 3, 0), (1, 0)

    Step-by-step explanation:

    To find the x - intercepts, let y = 0, that is

    3x² + 6x - 9 = 0 (divide through by 3)

    x² + 2x - 3 = 0 ← in standard form

    (x + 3) (x - 1) = 0 ← in factored form

    Equate each factor to zero and solve for x

    x + 3 = 0 ⇒ x = - 3

    x - 1 = 0 ⇒ x = 1

    The x - intercepts are ( - 3, 0), (1, 0)
