The question is in the attachment.
Quick translation(please forgive my poor English):

Point A(-2,2√3),Point B(1,0). P is a moving point along x-axis. Line QP is perpendicular to the line AP. M is the middle point of the line PQ. Please calculate the minimum value of line segment BM.

I don't think you mean that QP is perpendicular to AP; the picture says that QA is perpendicular to AP.

Here is the (rather poor) translation I get from one site:

I suspect that what this really means is "the perpendicular line to AP at A intersects the y-axis at point Q".

You put this under geometry, but it sounds like a place to use calculus. Is that available to you? I haven't tried solving this yet, before knowing what you can do or what you have done.
