`9x^(2) +2hxy +4y^(2) +6x +2fy - 3 = 0` represents two parallel lines. Then

If ax^(2)+2hxy+by^(2)+2gx+2fy+c=0 represents two parallel straight lines, then

IF the equation x^(2) + y^(2) + 2gx + 2fy + 1 = 0 represents a pair of lines, then

If the equation ax^(2)+2hxy+by^(2)+2gx+2fy+c=0 represents a pair of parallel lines, then

If the equation 2x^(2)+2hxy +6y^(2) - 4x +5y -6 = 0 represents a pair of straight lines, then the length of intercept on the x-axis cut by the lines is equal to

The principal axes of the hyperbola ax^(2) + 2hxy + by^(2) + 2gx + 2fy + c = 0 are parallel to the lines

If ax^(2)+2hxy+by^(2)+2gx+2fy+c=0 represents parallel straight lines, then

If 9x^(2)-24xy+ky^(2)-12x+16y-12=0 represents a pair of parallel lines then k=

If the equation ax^(2)+2hxy+by^(2)+2gx+2fy+c=0 resents a pair of parallel lines then prove that
