(A) Let the roots be $x_1 = \frac{\alpha}{\alpha - 1}$ and $x_2 = \frac{\alpha + 1}{\alpha}$.From the relation between roots and coefficients,the sum of roots is $x_1 + x_2 = -\frac{b}{a}$ and the product of roots is $x_1 x_2 = \frac{c}{a}$.Product of roots: $\frac{\alpha}{\alpha - 1} 	imes \frac{\alpha + 1}{\alpha} = \frac{\alpha + 1}{\alpha - 1} = \frac{c}{a}$.By componendo and dividendo,$\frac{(\alpha + 1) + (\alpha - 1)}{(\alpha + 1) - (\alpha - 1)} = \frac{c + a}{c - a} \implies \frac{2\alpha}{2} = \frac{c + a}{c - a} \implies \alpha = \frac{c + a}{c - a}$.Sum of roots: $\frac{\alpha^2 + \alpha^2 - 1}{\alpha(\alpha - 1)} = \frac{2\alpha^2 - 1}{\alpha^2 - \alpha} = -\frac{b}{a}$.Substituting $\alpha$ and simplifying,we find that $(a + b + c)^2 = b^2 - 4ac$.

If the roots of the equation $ax^2 + bx + c = 0$ are real and of the form $\frac{\alpha}{\alpha - 1}$ and $\frac{\alpha + 1}{\alpha}$,then the value of $(a + b + c)^2$ is
