Application +4 | -1

If the bisectors of angles represented by

a{x^2} + 2hxy + b{y^2} = 0

and

a'{x^2} + 2h'xy + b'{y^2} = 0

are same, then

View answer and explanation

Correct option: A

\left( {a - b} \right)h' = \left( {a' - b'} \right)h

The correct answer is A ((a - b)h' = (a' - b')h) because the condition for the bisectors of two pairs of lines to be the same is used.
