  • $A(x-x_1)+B(y-y_1)+C(z-z_1)=0$
Step 1:
Let the equation of the plane containing the given point $(1,-1,2)$ is
(i.e) $A(x-1)+B(y+1)+c(z-2)=0$------(1)
Applying the condition of perpendicularly to the plane in equ(1) with the plane
$2x+3y-2z=5$ and $x+2y-3z=8$
We have $2A+3B-2C=0$ and $A+2B-3C=0$
Step 2:
Let us solve three two equations,we get
The required equation is
