Analyzing +4 | -1

If the equation

x^4+b x^3 y+c x^2 y^2+d x y^3+e y^4=0

represents two pairs of perpendicular lines, then

View answer and explanation

Correct option: B

b+d=0

and

e=-1

Option B (

b+d=0

and

e=-1

) is correct because it represents the condition when the given equation represents two pairs of perpendicular lines, derived from comparing coefficients.
