To rewrite the expression \( 2(x+1)(x+2) \), we first need to expand it.
1. Expand \( (x+1)(x+2) \):
\[
(x+1)(x+2) = x^2 + 2x + 1x + 2 = x^2 + 3x + 2
\]
2. Now, multiply by 2:
\[
2(x^2 + 3x + 2) = 2x^2 + 6x + 4
\]
Therefore, the expression \( 2(x+1)(x+2) \) can be rewritten as \( 2x^2 + 6x + 4 \).
So the correct response is:
**2x² + 6x + 4**.
