(1 point)
Responses

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

2x2+3x+2
2 x squared plus 3 x plus 2

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

2x2+6x+4

Answer 1

To simplify the expression \(2(x+1)(x+2)\), we can start by expanding the binomials:

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 rewritten as:

**2x² + 6x + 4**

Therefore, the correct answer is:

**2x² + 6x + 4**
