The equation `y=sinxsin(x+2)-sin^(2)(x+1)` represents a straight line lying in

if y=sin x*sin(x+2)-sin^(2)(x+1) represents a straight line,then its passes through

The equation x^(3)+x^(2)y-xy^(2)-y^(3)=0 represents three straight lines passing through the origin such that

The equation x^(3)+x^(2)y-xy^(2)-y^(3)=0 represents three straight lines passing through the origin such that

The equation (x+y+1)^(2)+k(x^(2)+y^(2)+1)=0 represents two straight lines then one of the possible values of k is

a(x^(2)-y^(2))+xy=0 represents a pair of straight lines for

a(x^(2)-y^(2))+xy=0 represents a pair of straight lines for

The condition that the equation ax^(2)+by^(2)+c(x+y)=0 to represents a pair of straight lines is

Does x^(2)+y^(2)=0 represent a pair of straight lines

The value of k, so that the equation -2x^(2)+xy+y^(2)-5x+y+k=0 may represent straight line is
