WebIf the roots of the equation (b - c) x2 + (c - a)x + (a - b) = 0 be equal, then prove that a, b, c are in arithmetic progression. Solution Given, (b-c) x2 + (c - a)x + (a - b) = 0 Comparing given equation with general form Ax3+Bx+C= 0 We get, A=(b−c),B=(c−a),D= (a−b) If roots are equal then discriminant is equal to zero. That is, D= B2−4AC =0
