Let the slopres of the lines be m and m'.


 Now , m+m'=-2h/b , m*m'=a/b.


Since one of the lines bisects the angle between the +ve direction of the axes this means slope of one of them is 1.


Let m=1. Therefore , m'=a/b.


=> m+m'=1+a/b.


=>-2h/b=1+a/b.


=>a+b+2h=0. Hence, the result.

let the slopes of the lines of the pair ax^2+2hxy+by^2=0 is m & m


Now , m+m=-2h/b , m*m=a/b.


> m+m=1+a/b.


> -2h/b=1+a/b.


> a+b+2h=0.
