Question
The equation of a plane bisecting the angle between the plane 2x - y + 2z + 3 = 0 and 3x - 2y + 6z + 8 = 0 is -
Options
A.5x - y - 4z - 45 = 0
B.5x - y - 4z - 3 = 0
C.23x - 13y + 32z + 45 = 0
D.23x - 13y + 32z + 5 = 0
Solution
Equation of bisector of plane
⇒
⇒ 14x - 7y + 14z + 21 = ± (9x - 6y + 18z + 24)
⇒ 5x - y - 4z = 3 and
23x - 13y + 32 z + 45 = 0
⇒
⇒ 14x - 7y + 14z + 21 = ± (9x - 6y + 18z + 24)
⇒ 5x - y - 4z = 3 and
23x - 13y + 32 z + 45 = 0
