    Another vector qn

    I found one more question, sorry for this!

    Find the points on the line with parametric equations x=2-t, y=3+2t and z=1+t which are 5sqrt(3) units from the point (1,0,-2)

    I found the line from the line parametric equations x=2-t, y=3+2t and z=1+t and the point (1,0,-2) thinking that it will equal to 5aqrt(3) but it was not so my whole concept is wrong. What are the steps here?

    Thank you so so so much again!

    Solve: [(2-t)-1]^2+[3+2t]^2+[(1+t)+2]^2=75.
