Advanced Math practice question

Answer: A. (2x + 1)(x + 3)

Both terms share the factor (x + 3): (x + 3)(2x + 1).

Why the other answers are wrong

B. (2x + 3)(x + 1)

This expands to 2x² + 5x + 3, not 2x² + 7x + 3.

C. 2x² + 3

This drops the 6x + x terms.

D. (x + 3)²

The other factor is 2x + 1, not x + 3.
