If the straight lines ax+ by+ 2hxy + 2gx + 2fy + c = 0 intersects x-axis, then

1). ag = fh

2). ah = fg

3). af = gh

4). None of these

Dear Student,
Please find below the solution to the asked query:

We know that point of intersection of ax2+by2+2hxy+2gx+2fy+c=0 ishf-bgab-h2,hg-afab-h2 Memorize itAs lines intersect at x-axis, hence y-coordinate is 0.hg-afab-h2=0hg-af=0af=gh Option 3
