`x^(2)-(a+b)x+ab`

If sin A and sin B of a triangle ABC satisfy c^(2)x^(2)-c(a+b)x+ab=0, then the triangle is

If sin A , sin B are roots of c^(2) x^(2) - c ( a+b) x + ab = 0 , then the Delta le is

If the since of the angles A and B of a triangle ABCsatisfy the equation c^2x^2-c(a+b)x+ab=0, then the triangle

Factors of x^(2) + x (a+ b) + ab = ………………..
