If two of the three lines represented by `ax^3+ bx^2y +cxy^2+dy^3=0` may be at right angles then

Find the condition that two of the three lines represented by ax^3+bx^2y+cxy^2+dy^3=0 may be at right angle.

Show that the condition that two of the three lines represented by ax^(3)+bx^(2)y+cxy^(2)+dy^(3)=0 may be at right angles is a^(2)+ac+bd+d^(2)=0

Statement I. Two of the straight lines represented by dx^3+cx^2y+bxy^2+ay^3=0 will be at right angles if d^2+bd+bc +a^2 =0 Statement II. Product of the slopes of two perpendicular line is -1

If two of the lines represented by ax^4 +bx^3y +cx^2 y^2+dxy^3+ay^4=0 bisects the angle between the other two, then

If two of the lines represented by ax^4 +bx^3y +cx^2 y^2+dxy^3+ay^4=0 bisects the angle between the other two, then

Statement-I : If two of the lines represented by ax^(3) + bx^(2)y + cxy^(2) + dy^(3) = 0 (a ne 0) make complementary angles with x-axis in anti-clockwise sense then slope of third line is a/d. Statement-II : If the slope of one of the line represented by ax^(2) + 2hxy + by^(2) = 0 is 'n' times the slope of another then ((1+n)^(2))/(n)=(h^(2))/(a b) Which of the above statement is correct :
