Multiply and simplify:



[tex](3x + 5)(2x^2 - 3x + 2)[/tex]



A. [tex]6x^3 + 19x^2 + 21x + 10[/tex]



B. [tex]16x^3 - 24x + 16[/tex]



C. [tex]6x^3 - 9x^2 + 6x[/tex]



D. [tex]6x^3 + x^2 - 9x + 10[/tex]

Answer :

- Distribute $(3x+5)$ over $(2x^2 - 3x + 2)$.
- Expand each term: $6x^3 - 9x^2 + 6x + 10x^2 - 15x + 10$.
- Combine like terms: $6x^3 + (-9x^2 + 10x^2) + (6x - 15x) + 10$.
- Simplify to get the final expression: $\boxed{6x^3 + x^2 - 9x + 10}$.

### Explanation
1. Understanding the Problem
We are given the expression $(3 x+5)(2 x^2-3 x+2)$ to multiply and simplify. Our goal is to expand this product and combine like terms to arrive at a simplified polynomial.

2. Distributing the Terms
To multiply the two polynomials, we distribute each term in the first polynomial $(3x + 5)$ to each term in the second polynomial $(2x^2 - 3x + 2)$. This gives us:

$3x(2x^2 - 3x + 2) + 5(2x^2 - 3x + 2)$

3. Expanding the Terms
Now, we expand each term:

$3x(2x^2) + 3x(-3x) + 3x(2) + 5(2x^2) + 5(-3x) + 5(2)$

$= 6x^3 - 9x^2 + 6x + 10x^2 - 15x + 10$

4. Combining Like Terms
Next, we combine like terms. We have the $x^3$ term, the $x^2$ terms, the $x$ terms, and the constant term:

$6x^3 + (-9x^2 + 10x^2) + (6x - 15x) + 10$

$= 6x^3 + x^2 - 9x + 10$

5. Final Result
Therefore, the simplified expression is $6x^3 + x^2 - 9x + 10$.

### Examples
Polynomial multiplication is used in various fields such as engineering, physics, and computer science. For example, in control systems, engineers use polynomials to model the behavior of a system, and multiplying these polynomials helps in analyzing the combined effect of different components. In computer graphics, polynomial multiplication is used to perform transformations and rendering of images.
