The expansion of the expression (x + 2y)² is x² + 4xy + 4y².
<h3>How to illustrate the information?</h3>
The given expression is (x + 2y)². The expansion of the expression will be:
(x + 2y)²
= (x + 2y)(x + 2y)
= x² + 2xy + 2xy + 4y².
= x² + 4xy + 4y²
The expansion is x² + 4xy + 4y².

Therefore, D =
- ![\[ \left[ {\begin{array}{ccc} 5 & 2 & -4\\ 1 & 12 & 3 \\ 11 & 3 & -2 \end{array} } \right]\]](https://tex.z-dn.net/?f=%5C%5B%20%20%5Cleft%5B%20%7B%5Cbegin%7Barray%7D%7Bccc%7D%20%20%205%20%26%202%20%26%20-4%5C%5C%20%20%201%20%26%2012%20%26%203%20%5C%5C%2011%20%26%203%20%26%20-2%20%20%5Cend%7Barray%7D%20%7D%20%5Cright%5D%5C%5D)
This becomes:
