15. The common perpendicular of two skew lines with direction vectors and is the line that intersects both the skew lines and has direction vector . Find the points of intersection of the common perpendicular with each of the lines and .
Thank you for your help.
However, I am not sure how to proceed from here.
I called the common perpendicular , whose vector equation is .
I then tried to find the points of intersection with the first given line ([x, y, z]) but I did not get useful solutions.
