(D) Given the equation: $\frac{x^2-bx}{ax-c} = \frac{m-1}{m+1}$ Cross-multiplying,we get: $(x^2-bx)(m+1) = (m-1)(ax-c)$ Expanding the terms: $x^2(m+1) - bx(m+1) = ax(m-1) - c(m-1)$ Rearranging into the standard quadratic form $Ax^2 + Bx + C = 0$: $x^2(m+1) - x(b(m+1) + a(m-1)) + c(m-1) = 0$ Let the roots be $p$ and $-p$. For a quadratic equation $Ax^2 + Bx + C = 0$,the sum of roots is given by $-\frac{B}{A}$. Since the sum of roots $p + (-p) = 0$,the coefficient of $x$ must be zero: $b(m+1) + a(m-1) = 0$ $bm + b + am - a = 0$ $m(a+b) = a-b$ Therefore,$m = \frac{a-b}{a+b}$

$A. \alpha + \beta + \gamma$	$(1) -\frac{43}{4}$
$B. \alpha^2 + \beta^2 + \gamma^2$	$(2) -\frac{7}{8}$
$C. \frac{1}{\alpha} + \frac{1}{\beta} + \frac{1}{\gamma}$	$(3) 86$
$D. \frac{\alpha}{\beta \gamma} + \frac{\beta}{\gamma \alpha} + \frac{\gamma}{\alpha \beta}$	$(4) 0$
	$(5) 10$

Let $a, b$ and $c$ be positive real numbers. If $\frac{x^2-bx}{ax-c} = \frac{m-1}{m+1}$ has two roots which are numerically equal but opposite in sign,then the value of $m$ is
