hello everyone please help me out in this question please
The planes p1 and p2 have equations X+Y-Z=0 AND 2X-4Y+Z+12=0 respectively.
1.) find the numbers p,q,r such that vector (p,q,r) is parallel to both p1 and p2
2.)hence find the equation of the plane through the point (3,8,2) which is perpendicular to both p1 and p2
answer:1.)p=1 q=1 r=2
2.)X+y+2z=15
guys pls explain me in lucid way
thanks
