Answer 1

Your answer ⤵

_______________________________

$x + 2y ( 2 ) \\ \\ 2 x + 4 y$

Or

${x + 2y }^{2} \\ \\ {x}^{2} + {2y}^{2} + 2 (x) (2y) \\ \\ {x}^{2} + {4y}^{2} + 4xy$

Answer 2

$\textbf {Hey there, here is the solution.}$

.............................................................................................

Algebraic Identify : (a + b)² = a² + 2ab + b²

.

We apply the above identify to the question:

(x + 2y)² = x² + 2(x)(2y) + (2y)²

(x + 2y)² = x² + 4xy + 4y²

..............................................................................................

Answer: x² + 4xy + 4y²
