Find the unit normal to the planea+ 2s- 2t= 15. What is the distance of the plane from the origin?

2. Relevant equations

The normal to a plane is given bysxt

For any plane,r.n= p [n = unit vector and p = constant]

3. The attempt at a solution

Not entirely sure what I'm meant to be doing here as I'm not given any real values for the vectorssandt, so I can't see how to crossing them achieves anything. I'd be capable of crossing the two vectors if they were in component form, but not here. Obviously I'm missing something here, any help would be great.

Many thanks,

/Supra.
