Answer:

B. 2x² + 3

Step-by-step explanation:

The given expression is

(3x² + 2x + 4) - (x² + 2x + 1)

To subtract the polynomials we need to write the expression without the parenthesis as

3x² + 2x + 4 - x² - 2x - 1

Now, we need to add the like terms

(3x² - x²) + (2x - 2x) + (4 - 1)

2x² + 0 + 3

2x² + 3

Therefore, the answer is

B. 2x² + 3
