Answer 1

To simplify the expression \( 2(x+1)(x+2) \), we can first expand the expression inside the parentheses and then multiply by 2.

1. Expand \( (x+1)(x+2) \): \[ (x+1)(x+2) = x^2 + 2x + x + 2 = x^2 + 3x + 2 \]

2. Now, multiply this result by 2: \[ 2(x^2 + 3x + 2) = 2x^2 + 6x + 4 \]

Thus, the expression \( 2(x+1)(x+2) \) can be rewritten as \( 2x^2 + 6x + 4 \).

So, the correct response is: 2x² + 6x + 4.
