Find the shortest distance between the skew-line4s `l_1:(x-1)/2=(y+1)/1=(z-2)/4` and `l_2 : (x+2)/4=(y-0)/(-3)=(z+1)/1`

Explanation

To find the shortest distance between the skew lines \( l_1 \) and \( l_2 \), we will follow these steps:

### Step 1: Identify the direction ratios and points on the lines

The equations of the lines are given as:

1. \( l_1: \frac{x-1}{2} = \frac{y+1}{1} = \frac{z-2}{4} \)
2. \( l_2: \frac{x+2}{4} = \frac{y-0}{-3} = \frac{z+1}{1} \)
