Statement -1 : There exists only one real value of ‘k’ for which the real roots of the equation are in H.P. because
Statement - 2 : For a cubical equation if b, c and d are non zero real and constant, then we can have only one real value of ‘a’ for which all real roots of are in H.P.

Consider a triangle ABC. BE and CF are the medians drawn through the angular points B and C respectively and G is the centroid of the ABC.
Statement – 1: If the points, A, E, G, F are concyclic then must be acute. because
Statement – 2: The medians of a triangle divide triangle into area wise two equal parts.
