Question

find the equation of the planes parallel to the plane x-2y+2z-3 = 0 which are at a unit distance from the point (1,2,3)​

Answer 1

Answer:

substitute the value one by one

Answer 2

Answer:

let's put x = 1 , y = 2 , z = 3

then u will get

1- 2 x 2 + 2 x 3 - 3 = 0

1 - 4 + 6 - 3 = 0

1 + 2 - 3 = 0

1 - 1 = 0

0 = 0
