Question

Find the expanded form of (2x+1/2y)^2

Answer 1

$(2x + \frac{1}{ 2y } ) {}^{2} \\ \\ = 4 {x}^{2} + \frac{1}{4{y}^{2} } + \frac{2x}{y}$
hope this helps you

Answer 2

(2x+1/2y)
$\frac{ {(4xy + 1)}^{2} }{ {(2y)}^{2} } \\ \frac{16 {(xy)}^{2} + 1 + 8xy }{4 {y}^{2} } \\ 4 {x}^{2} + \frac{1}{ {4} {y}^{2} } + \frac{2x}{y}$
