Question

4m/m^2 - 1+2/1-m - 1/m+1 Пжжжж​

Answer 1

Объяснение:

$\frac{4m}{m^2-1}+\frac{2}{1-m} -\frac{1}{m+1}=\frac{4m}{(m-1)*(m+1)}-\frac{2}{m-1}-\frac{1}{m+1}=\frac{4m-2*(m+1)-1*(m-1)}{(m-1)*(m+1)}=\\=\frac{4m-2m-2-m+1}{(m-1)*(m+1)} =\frac{m-1}{(m-1)*(m+1)}=\frac{1}{m+1}.$

Answer 2

It seems like you're providing a mathematical expression, but the formatting is unclear. It appears to be:

$\frac{4m}{m^2} - \frac{1 + 2}{1 - m} - \frac{1}{m + 1}$

To simplify this expression, let's work on it step by step.

First, let's simplify the first fraction $\frac{4m}{m^2}$ by factoring out the common factor of $m$:

$\frac{4m}{m^2} = \frac{4}{m}$

Next, let's simplify the second fraction $\frac{1 + 2}{1 - m}$ by combining the numerator:

$\frac{1 + 2}{1 - m} = \frac{3}{1 - m}$

Lastly, the third fraction $\frac{1}{m + 1}$ is already in its simplest form.

Now the expression becomes:

$\frac{4}{m} - \frac{3}{1 - m} - \frac{1}{m + 1}$

This expression cannot be simplified further without additional context or restrictions on the variable $m$. If you have specific values for $m$ or any other constraints, please provide them, and I can assist you further.
