Find the distance (d) and coordinates of Q1 (x, y, z) and Q2 (x, y, z)

Let L; be the line passing through the point P1={2, 7, 0) with direction vector E'I=[-1, 2, 2]T, and let L2 be the line passing through the point P3=(7, 5, 3) with direction vector EE=[1, D, -2]T. Find the shortest distance d between these two lines, and nd a point Q1 on L1 and a point Q; on L2 so that d(Q1,Q2) = (I. Use the square root symbol 'Vl' where needed to give an exact value for your answer. (i=0 Q1=(0,0,0) Q2=(o, o, 0)
