    The negative valued x-intercept is (-6, 0)

    Step-by-step explanation:

    Step 1: Factor

    3x^2 + 13x - 30

    (3x - 5) (x + 6)

    Step 2: Solve for x

    3x - 5 + 5 = 0 + 5 and x + 6 - 6 = 0 - 6

    3x / 3 = 5 / 3 and x = - 6

    x = 5/3 and x = - 6

    Answer: The negative valued x-intercept is (-6, 0)

    -6

    Step-by-step explanation:

    3x² + 13x - 30 = 0

    3x² + 18x - 5x - 30 = 0

    3x (x + 6) - 5 (x + 6) = 0

    (3x - 5) (x + 6) = 0

    x = 5/3, - 6
