Step 1

Given: The polynomial as$2{x}^{2}+4x+1$ ,

To determine: The factorization of the given polynomial.

Step 2

Explanation:

Factorizing the given polynomial:

The given polynomial can be rewritten as

$2{x}^{2}+4x+1$

$=2({x}^{2}+2x)+1$

$=2({x}^{2}+2x+1-1)+1$ [Addind and sutracting 1]

$=2({(x+1)}^{2}-1)+1$ [since $(a+b)}^{2}={a}^{2}+2ab+{b}^{2$ ]

$=2{(x+1)}^{2}-1$

$={\left(\sqrt{2}(x+1)\right)}^{2}-{1}^{2}$

$=(\sqrt{2}(x+1)-1)(\sqrt{2}(x+1)+1)$

[since${a}^{2}-{b}^{2}=(a-b)(a+b)$ ]

$=(\sqrt{2}x+\sqrt{2}-1)(\sqrt{2}x+\sqrt{2}+1)$

Answer:$2{x}^{2}+4x+1=(\sqrt{2}x+\sqrt{2}-1)(\sqrt{2}x+\sqrt{2}+1)$ .
