If the lines represented by `ax^2 + 4xy + y^2 + 8x + 2 fy+c=0` interseet on Y-axis, then `(f,c)=`

If the lines represented by ax^(2)+4xy+y^(2)+8x+2fy+c=0 interseet on Y -axis,then (f,c)=

IF the pair of lines represented by ax^(2)+2hxy+by^(2)+2gx+2fy+c=0 intersect on the y-axis, then show that 2fgh-bg^(2)-ch^(2)=0

Lines represented by 4x^(2)+4xy+y^(2)=0 are

If the pair of lines ax^(2) + 2hxy + by^(2)+ 2gx + 2fy + c = 0 intersect on the y-axis then

If the pair of lines ax^2 +2hxy+ by^2+ 2gx+ 2fy +c=0 intersect on the y-axis then

If the pair of lines ax^2 +2hxy+ by^2+ 2gx+ 2fy +c=0 intersect on the y-axis then

If the pair of lines ax^2 +2hxy+ by^2+ 2gx+ 2fy +c=0 intersect on the y-axis then

If the lines represented by ax^(2)+4xy+4y^(2)=0 are real distinct, then

If the pair of line ax^2+2hxy+by^2+2gx+2fy+c=0 intersect on the y-axis, then
