X+2/x-1+x+3/x+1+x+5/1-x^2=0

Answer 1

Ответ:

x+ 2\x + 3\x + x + 5 - x^2

3x + 2\x + x + 3\x + x + 5 - x^2

3x^2+2+3+5x-x^3\x

3x^2+5+5x-x^3\x

-x^3+3x^2+5x+5\x

вроде как правильно

Answer 2

Ответ:

3x(x+1)-(х+2)(x-1)

=2

3х(2)+3х-x(2)+x-2х+2-2

=0

2x(2)+2х=0

2x(х+1)=0

x=0

там, где одна цифра в скобках, это степень

Answer 3

To solve the equation:

X + 2/(X - 1) + X + 3/(X + 1) + X + 5/(1 - X^2) = 0,

we need to simplify the expression and find the common denominator.

Let's start by finding the common denominator. The common denominator will be (X - 1)(X + 1)(1 - X^2) since these are the denominators in the equation. Multiplying these terms, we get:

Common denominator = (X - 1)(X + 1)(1 - X^2) = (X^2 - 1)(1 - X^2) = (1 - X^4).

Now, we can rewrite the equation with the common denominator:

(X * (1 - X^4) + 2 * (1 - X^4)/(X - 1) + X * (1 - X^4) + 3 * (1 - X^4)/(X + 1) + X * (1 - X^4) + 5)/(1 - X^4) = 0.

Simplifying the numerator, we have:

X * (1 - X^4) + 2 * (1 - X^4)/(X - 1) + X * (1 - X^4) + 3 * (1 - X^4)/(X + 1) + X * (1 - X^4) + 5

= X - X^5 + (2 * (1 - X^4))/(X - 1) + X - X^5 + (3 * (1 - X^4))/(X + 1) + X - X^5 + 5

Now, we can combine like terms:

= 3X - 3X^5 + (2 * (1 - X^4))/(X - 1) + (3 * (1 - X^4))/(X + 1) + 5.

Now, we can simplify the equation further:

(3X - 3X^5 + 2(1 - X^4))/(X - 1) + (3(1 - X^4))/(X + 1) + 5 = 0.

Multiplying both sides of the equation by (X - 1)(X + 1), we get:

(3X - 3X^5 + 2(1 - X^4))(X + 1) + (3(1 - X^4))(X - 1) + 5(X - 1)(X + 1) = 0.

Expanding and simplifying the equation, we have:

3X^2 - 3X^6 + 2X + 2 - 2X^4 - 2 + 3X - 3X^4 + 3 - 3X^4 + 3X^2 - 3 - 5X^2 + 5 = 0.

Combining like terms:

-3X^6 - 10X^4 + 8X^2 + 5X - 4 = 0.

This is a sixth-degree polynomial equation. Solving it directly can be quite challenging. You may need to use numerical methods or software to approximate the solutions.

Alternatively, if you have specific values for X in mind, you can substitute them into the equation to check if they satisfy it.
