If the equation `2x^2+k x y+2y^2=0` represents a pair of real and distinct lines, then find the values of `kdot`

If the equation 2x^(2)+kxy+2y^(2)=0 represents a pair of real and distinct lines, then find the values of k.

If the equation 2x^(2)+lambdaxy+2y^(2)=0 represents a pair of real and distinct lines, then

Statement-I : If the equation 4x^(2)+mxy-3y^(2)=0 represents a pair of real and distinct lines then m in R . Statement-II : If the difference of the slopes of the lines kx^(2)-12xy + y^(2) = 0 is 2 then k is 30 Which of the above statement is correct :

The set of value of h for which the equation 4x^(2)+hxy-3y^(2)=0 represents a pair of real and distinct lines is

The set of value of h for which the equation 4x^(2)+hxy-3y^(2)=0 represents a pair of real and distinct lines is

If the equation 3x^(2)+xy-y^(2)-3x+6y+k=0 represents a pair of straight lines, then the value of k, is

If the equation 3x^(2)+xy-y^(2)-3x+6y+k=0 represents a pair of straight lines, then the value of k, is

The equation x^(2)+kxy+y^(2)-5x-7y+6=0 represents a pair of straight lines, then k is

The equation x^(2)+kxy+y^(2)-5x-7y+6=0 represents a pair of straight lines, then k is

If the equation x^(2)+3xy+2y^(2)+x-y+k=0 represents a pair of line, then k=
