The expressions are simplified to 2x and $\frac{2}{(x+ 1)(x - 1)}$

<h3>How to simply the expressions</h3>

Given the expression;

$\frac{8x^2 - 4x}{4x - 2}$

Let's factorize the numerator;

$\frac{2x( 4x - 2)}{4x - 2}$

Factor the common terms, we have;

2. $\frac{1}{x-1} - \frac{2}{x} + \frac{1}{x + 1}$

Find the Lowest common multiple

$\frac{x(x+ 1) - 2 (x+ 1)(x - 1) + x(x-1)}{x(x-1)(x+ 1)}$

expand the brackets

$\frac{x^2 + x -2(x^2 -x + x -1) + x^2 -x}{x(x-1)(x+ 1)}$

$\frac{x^2+x - 2x^2 -2 + 2x + 2 + x^2 - x}{x(x+1) (x -1)}$

collect like terms

$\frac{2x}{x(x+ 1) (x-1)}$

Divide common terms

$\frac{2}{(x+ 1)(x - 1)}$

Thus, the expressions are simplified to 2x and $\frac{2}{(x+ 1)(x - 1)}$

IS THIS CORRECT!!!!!!!!!!!!!

Nadusha1986 [10]

For this case, the first thing we must do is define variables.
We have then:
x: number of devices.
Y: plan charge
For the current plan we have:
 $y = 175
$
 For the new plan we have:
 $y = 4.5x + 94
$
 Since we want the new plan to be smaller than the current plan, then we have:
 $175\ \textgreater \ 4.5x + 94
$
 From here, we clear the value of x:
 $4.5x \ \textless \ 175 - 94

x \ \textless \ 81 / 4.5

x \ \textless \ 18$
 Answer:
x <18
Note: The graph is correct
