(B) Since $\alpha$ and $\beta$ are roots of $ax^2 + bx + c = 0$,we have $a\alpha^2 + b\alpha + c = 0$ and $a\beta^2 + b\beta + c = 0$.From $a\alpha^2 + b\alpha + c = 0$,we get $\alpha(a\alpha + b) = -c$,so $(a\alpha + b) = -\frac{c}{\alpha}$.Similarly,$(a\beta + b) = -\frac{c}{\beta}$.Substituting these into the expression:$\frac{1}{(a\alpha + b)^2} + \frac{1}{(a\beta + b)^2} = \frac{1}{(-c/\alpha)^2} + \frac{1}{(-c/\beta)^2} = \frac{\alpha^2}{c^2} + \frac{\beta^2}{c^2} = \frac{\alpha^2 + \beta^2}{c^2}$.Using the identity $\alpha^2 + \beta^2 = (\alpha + \beta)^2 - 2\alpha\beta$,where $\alpha + \beta = -\frac{b}{a}$ and $\alpha\beta = \frac{c}{a}$:$\frac{(\alpha + \beta)^2 - 2\alpha\beta}{c^2} = \frac{(-b/a)^2 - 2(c/a)}{c^2} = \frac{b^2/a^2 - 2c/a}{c^2} = \frac{b^2 - 2ac}{a^2c^2}$.

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