will start,

if a pair of straight lines i given

in the form- ax^2+bx^2....(usual one)

then the intersection points of the lines can be obtained by differentiating the equations with respect to x and then y

after doing this u will get two equations solving which u will get the intersection point

for eg. 2x^2+4xy +3y^2+2y+5x+2=0

diff. w.r.t. to x
we have

4x+4y+5=0 here terms independent of x are constants

diff. w.r.t. y

6y+4x+2=0 here terms independent of y are constants

solvingthe two u will get ur intersection point
which comes to be (-11/4 ,3/2)

plsss rate me for this knowledge(some may be knowing this!!!)

IIT- Imposible Is This(atleast fr meeeeeeeee)
