$$\frac{16x^2}{8x^2 - 32x} - \frac{2x^2 - 32}{x^2 - 8x + 16}$$
Упростим выражение:
$$\frac{16x^2}{8x(x - 4)} - \frac{2(x^2 - 16)}{(x - 4)^2} = \frac{2x}{x - 4} - \frac{2(x - 4)(x + 4)}{(x - 4)^2} = \frac{2x}{x - 4} - \frac{2(x + 4)}{x - 4} = \frac{2x - 2x - 8}{x - 4} = \frac{-8}{x - 4}$$
Подставим x = 3.96:
$$\frac{-8}{3.96 - 4} = \frac{-8}{-0.04} = 200$$
Ответ: **200**
