Question

Помогите упростить выражение,пожалуйста.
(y-9)(y²-64)/(y-8)(y-8)²

Answer 1

Ответ:

$\frac{(y - 9)(y {}^{2} - 64) }{(y - 8)(y - 8) {}^{2} } = \frac{(y - 9) \times (y - 8) \times (x + 8)}{(y - 8) {}^{3} } = \frac{(y - 9) \times (y + 8)}{(y - 8) {}^{2} } = \frac{y {}^{2} + 8y - 9y - 72}{(x - 8) {}^{2} } = \frac{y {}^{2} - y - 72 }{(y - 8) {}^{2} }$

Answer 2

Ответ:

(y-9)(y-8)(y+8)/(y-8)^3

(y-9)(y+8)/(y-8)^2

y^2+8y-9y-72/(y-8)^2

y^2-y-72/(y-8)^2
