What is the difference?
slega [8]

Answer:

<h3>The answer is option D.</h3>

Step-by-step explanation:

First we must first find the LCM

The LCM of x² + 3x + 2 and (x + 2)(x + 1 ) is

x² + 3x + 2

So we have

\frac{x}{ {x}^{2} + 3x + 2 }  -  \frac{1}{(x + 2)(x + 1)}  \\  \\  =  \frac{x - 1}{ {x}^{2} + 3x + 2 }

Hope this helps you
