Answer
The polynomial \( x^{3}+x^{2}+2x+2 \) factors to \( (x + 1)(x^{2} + 2) \).
Solution
Factor the expression by following steps:
- step0: Factor:
\(x^{3}+x^{2}+2x+2\)
- step1: Calculate:
\(x^{3}+2x+x^{2}+2\)
- step2: Rewrite the expression:
\(x\times x^{2}+x\times 2+x^{2}+2\)
- step3: Factor the expression:
\(x\left(x^{2}+2\right)+x^{2}+2\)
- step4: Factor the expression:
\(\left(x+1\right)\left(x^{2}+2\right)\)
Let's factor the polynomial \( x^{3}+x^{2}+2x+2 \) step by step.
1. **Group the terms**: We can group the polynomial into two parts:
\[
(x^{3} + x^{2}) + (2x + 2)
\]
2. **Factor out common factors from each group**:
- From the first group \( x^{3} + x^{2} \), we can factor out \( x^{2} \):
\[
x^{2}(x + 1)
\]
- From the second group \( 2x + 2 \), we can factor out \( 2 \):
\[
2(x + 1)
\]
3. **Combine the factored groups**:
Now we can combine the factored terms:
\[
x^{2}(x + 1) + 2(x + 1)
\]
4. **Factor out the common binomial factor \( (x + 1) \)**:
\[
(x + 1)(x^{2} + 2)
\]
Thus, the factored form of the polynomial \( x^{3}+x^{2}+2x+2 \) is:
\[
(x + 1)(x^{2} + 2)
\]
For the second polynomial, it seems there was an error in the input provided ("2."). If you have another polynomial to factor, please provide it, and I will assist you with that as well!

Beyond the Answer
To factor the polynomial \( x^{3}+x^{2}+2x+2 \), we can group the terms. First, group them as follows: \[ (x^{3} + x^{2}) + (2x + 2) \] Factoring each group gives us: \[ x^{2}(x + 1) + 2(x + 1) \] Notice that \( (x + 1) \) is a common factor, so we can factor that out: \[ (x + 1)(x^{2} + 2) \] Now, \( x^{2} + 2 \) cannot be factored further using real numbers, but you could express it as \( (x + \sqrt{2}i)(x - \sqrt{2}i) \) if you venture into complex numbers. Therefore, the complete factorization over the reals is: \[ (x + 1)(x^{2} + 2) \]
