Find the direction ratios of the normal to the plane x + 2y - 3z = 5.
Given :
Equation of plane : x + 2y – 3z = 5
To Find : direction ratios of normal
Answer :
Given equation of plane : x + 2y – 3z = 5
It can be written as
Comparing with 
Therefore, normal vector is 
Hence, direction ratios of normal are (1, 2, -3).
