Answer 2

Multiplying Expressions

Let's multiply the given expressions step by step.

1. (3-y)(3x+y) - Multiply each term in the first expression by each term in the second expression and then combine like terms.

The product of (3-y)(3x+y) is: ``` 9x - 3xy + 3yx - y^2 ```

The simplified result is: ``` 9x + xy - y^2 ```

2. (4a-1)(4a+1) - Apply the same process as above to find the product.

The product of (4a-1)(4a+1) is: ``` 16a^2 - 4a + 4a - 1 ```

The simplified result is: ``` 16a^2 - 1 ```

3. (x+8)(x+5) - Follow the same steps to find the product.

The product of (x+8)(x+5) is: ``` x^2 + 5x + 8x + 40 ```

The simplified result is: ``` x^2 + 13x + 40 ```

4. (3b-2)(2-4b) - Proceed with the multiplication process.

The product of (3b-2)(2-4b) is: ``` 6 - 12b - 4b + 8b^2 ```

The simplified result is: ``` 6 - 16b + 8b^2 ```

[[SOURCE #5]]

5. (6a+x)(2a*3x) - Apply the same method to find the product.

The product of (6a+x)(2a*3x) is: ``` 12a^2x + 18ax^2 + 2ax + 3x^2 ```

The simplified result is: ``` 12a^2x + 18ax^2 + 2ax + 3x^2 ```
