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

    Step-by-step explanation:

    Given

    x² + 4x + 3 = 0

    Consider the factors of the constant term ( + 3) which sum to give the coefficient of the x - term ( + 4)

    The factors are + 3 and + 1, since

    3 * 1 = 3 and 3 + 1 = 4, thus

    (x + 3) (x + 1) = 0

    Equate each factor to zero and solve for x

    x + 3 = 0 ⇒ x = - 3

    x + 1 = 0 ⇒ x = - 1

    Coordinates of roots are ( - 3, 0) and ( - 1, 0)
