Question

can somebody please help me with this question I've spent more than 3 hours on this, still nothing

Let L1 be the line passing through the point P1=(2, −4, −6) with direction vector →d1=[1, 0, 2]T, and let L2 be the line passing through the point P2=(−2, 3, −3) with direction vector →d2=[1, 4, −2]T.
Find the shortest distance d between these two lines, and find a point Q1 on L1 and a point Q2 on L2 so that d(Q1,Q2) = d. Use the square root symbol '√' where needed to give an exact value for your answer.
d = 
Q1(_ _ _) 
Q2(_ _ _)

Answer 1

google is your friend:

Answer 2

I have found d, my problem is finding Q1 and Q2

and if you don't want to help it's better not to say anything at all I know how to google thanks!
