Answer:

The answer is

3x⁴ + 7x³ + 7x² - 5x + 4

Explanation:

(x² + 3x + 4)(3x² - 2x + 1)

Expand the terms

We have

3x⁴ - 2x³ + x² + 9x³ - 6x² + 3x + 12x² - 8x + 4

Group like terms

That's

3x⁴ - 2x³ + 9x³ + x² - 6x² + 12x² + 3x - 8x + 4

Simplify

We have the final answer as

3x⁴ + 7x³ + 7x² - 5x + 4

Hope this helps you
