x2+6x+2
x squared plus 6 x plus 2

2x2+5x+2
2 x squared plus 5 x plus 2

2x2+3x+2

Answer 1

To simplify the expression \(2(x+1)(x+2)\), let's first expand it step by step:

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

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

So, the expression \(2(x+1)(x+2)\) can be written as:
\[
2x^2 + 6x + 4
\]

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