Question
To find the expression equivalent to \(\frac{3x^2 + 2x - 5x - 2x^2 + 2}{(x-2)(x-1)(x+2)(x-2)(x+1)(x+2)}\), we will first simplify the numerator.
1. **Simplify the Numerator:**
\[
3x^2 + 2x - 5x - 2x^2 + 2
\]
Combine like terms:
\[
(3x^2 - 2x^2) + (2x - 5x) + 2 = x^2 - 3x + 2
\]
2. **Factor the Numerator:**
The expression \(x^2 - 3x + 2\) can be factored as follows:
\[
x^2 - 3x + 2 = (x-1)(x-2)
\]
3. **Identify and Simplify the Denominator:**
The denominator is:
\[
(x-2)(x-1)(x+2)(x-2)(x+1)(x+2)
\]
Notice that \((x-2)\) and \((x+2)\) repeat, so we can rewrite the denominator as:
\[
(x-1)(x-2)^2 (x+2)^2 (x+1)
\]
4. **Write the Complete Expression:**
Now we put the numerator and denominator together:
\[
\frac{(x-1)(x-2)}{(x-1)(x-2)^2 (x+2)^2 (x+1)}
\]
5. **Cancel Common Factors:**
We can cancel \((x-1)\) and \((x-2)\) from the numerator and denominator:
\[
\frac{1}{(x-2)(x+2)^2 (x+1)}
\]
Thus, the simplified expression is:
\[
\frac{1}{(x-2)(x+2)^2 (x+1)}

To simplify the expression
\[
\frac{3x^2 + 2x - 5x - 2x^2 + 2}{(x-2)(x-1)(x+2)(x-2)(x+1)(x+2)},
\]
let's break it down step by step!
### Step 1: Simplify the Numerator
We start with the numerator:
\[
3x^2 + 2x - 5x - 2x^2 + 2
\]
We can combine the like terms:
- The \(x^2\) terms: \(3x^2 - 2x^2 = 1x^2\) (or just \(x^2\))
- The \(x\) terms: \(2x - 5x = -3x\)
- And we have a constant term: \( +2\)
Putting all this together, we get:
\[
x^2 - 3x + 2
\]
### Step 2: Factor the Numerator
Now, we need to factor \(x^2 - 3x + 2\). We are looking for two numbers that multiply to \(2\) and add to \(-3\). These numbers are \(-1\) and \(-2\). So we can factor it as:
\[
(x-1)(x-2)
\]
### Step 3: Simplify the Denominator
Next, let's look at the denominator:
\[
(x-2)(x-1)(x+2)(x-2)(x+1)(x+2)
\]
Notice that \((x-2)\) appears twice and \((x+2)\) appears twice too. We can rewrite it as:
\[
(x-1)(x-2)^2(x+2)^2(x+1)
\]
### Step 4: Put It All Together
Now we combine the simplified numerator and denominator:
\[
\frac{(x-1)(x-2)}{(x-1)(x-2)^2(x+2)^2(x+1)}
\]
### Step 5: Cancel Common Factors
Next, we can cancel out the common factors from the top and bottom. The \( (x-1) \) cancels out, and so does one \( (x-2) \):
\[
\frac{1}{(x-2)(x+2)^2(x+1)}
\]
### Final Answer
So, the final simplified expression is:
\[
\frac{1}{(x-2)(x+2)^2(x+1)}
\]
