The equation to the plane through the line of intersection of 2x+y+3z−2=0,x−y+z+4=0 such that each plane is at a distance of 2 unit from the origin is
x+y+2z+13=0,x+y+z−3=0
2x+y−2z+3=0,x−2y−2z−3=0
15x−12y+16z+50=0, x+2y+2z−6=0
x-y+2z-13=0, x+y-z-3=0
Equation of the plane is (2x+y+3z−2)+k(x−y+z+4)=0
p=|−2+4k|(2+k)2+(1−k)2+(3+k)2=2
⇒k=13,−1
∴ Planes are (2x+y+3z−2)+13
(x−y+z+4)=0,(2x+y+3z−2)−1
(x−y+z+4)=0
⇒15x−12y+16z+50=0,x+2y+2z−6=0
