    Answer:

    (- 1.5, 0 )

    Step-by-step explanation:

    The axis of symmetry is midway between the x- intercepts , where it crosses the x- axis, then

    5.5 – 2 = 3.5 ← distance from x = 2 to (5.5, 0 )

    The other x- intercept is to the left of x = 2

    2 – 3.5 = – 1.5

    The parabola crosses the x- axis at (- 1.5, 0 )
