Analysis of the 20 12 Middle School Entrance Examination of One Model Mathematics in Dongcheng District 17. ask for advice
When y=0, x=-n and x=2. Because the parabola y=(x+n)(x-2) intersects the X axis at point A and point B, where n >;; 0, point A is to the left of point B, so the coordinate of point A is (-n, 0).

When x=0, y=-2n, so C(0, -2n).
