Question

1 1 1 --------- - -------- = --- x(x-1) (x+1)² 12

Answer 1

Ответ:

1. нужно раскрыть скобки.

2х-1х*х+1 в степени 2 *12

2. вычисляем то что есть

1х*12=12х

Answer 2

To solve the equation:

(1/1) - (1/12) = (1/x) * (x-1) * (x+1)^2

First, simplify the left-hand side:

(12/12) - (1/12) = (11/12)

The equation becomes:

(11/12) = (1/x) * (x-1) * (x+1)^2

Next, multiply both sides by x to eliminate the fraction:

11x = (x-1) * (x+1)^2

Expand the right-hand side:

11x = (x-1) * (x+1) * (x+1)

11x = (x^2 - 1) * (x+1)

Now, distribute the terms on the right-hand side:

11x = x^3 + x^2 - x - 1

Rearrange the equation and set it equal to zero:

x^3 + x^2 - 11x - 1 = 0

At this point, you can solve this cubic equation using numerical methods or graphing software to find the approximate values of x that satisfy the equation. There is no simple algebraic solution for cubic equations in general.
