what is the correct answer in trigonometric identities. DiViDE ; x^5 + 5x^4 - 2x^3 + 3x^2 + 2x + 1 by x + 3

To divide the polynomial \(x^5 + 5x^4 - 2x^3 + 3x^2 + 2x + 1\) by \(x + 3\), you can use polynomial long division. Here are the step-by-step instructions:

1. Start by writing the polynomial division problem in long division format, with the dividend on the left (\(x^5 + 5x^4 - 2x^3 + 3x^2 + 2x + 1\)) and the divisor (\(x + 3\)) on the left. It should look like this:

```
______________________
x + 3 | x^5 + 5x^4 - 2x^3 + 3x^2 + 2x + 1
```

2. Divide the first term of the dividend (\(x^5\)) by the first term of the divisor (\(x\)). The result is \(x^4\). Write this above the line.

```
x^4
______________________
x + 3 | x^5 + 5x^4 - 2x^3 + 3x^2 + 2x + 1
```

3. Multiply the divisor (\(x + 3\)) by the quotient term you just found (\(x^4\)). The result is \(x^5 + 3x^4\). Write this under the dividend, lined up with the appropriate terms:

```
x^4
______________________
x + 3 | x^5 + 5x^4 - 2x^3 + 3x^2 + 2x + 1
-(x^5 + 3x^4)
```

4. Subtract the product you just found (\(x^5 + 3x^4\)) from the dividend. Write the result below the line:

```
x^4
______________________
x + 3 | x^5 + 5x^4 - 2x^3 + 3x^2 + 2x + 1
-(x^5 + 3x^4)
___________________
2x^4 - 2x^3
```

5. Bring down the next term from the dividend, which is \(2x^3\). Write it next to the previous result:

```
x^4 + 2x^3
______________________
x + 3 | x^5 + 5x^4 - 2x^3 + 3x^2 + 2x + 1
-(x^5 + 3x^4)
___________________
2x^4 - 2x^3
-(2x^4 + 6x^3)
```

6. Repeat steps 3-5 with the new dividend (\(2x^4 - 2x^3\)) and the divisor (\(x + 3\)). In each step, find the next quotient term by dividing the first term of the new dividend by the first term of the divisor, and subtract the product from the new dividend.

Continue these steps until you have a remainder with a lower degree than the divisor. The final result of the division will be the quotient.

Note: Since the given problem involves polynomial division, it does not relate directly to trigonometric identities. Trigonometric identities involve relationships between trigonometric functions like sine, cosine, and tangent.
