МОЭНО ПОДРОБНОЕ РЕШЕНИЕ ПЛЗ​

Answer 1

Ответ:

$2x + 2y$

Объяснение:

$(x - \frac{ {y}^{2} }{x} ) \div ( \frac{1}{2} - \frac{y}{2x} ) = \frac{x {}^{2} - y {}^{2} }{x} \div \frac{x - y}{2x} = \frac{(x + y)(x - y)}{x} \times \frac{2x}{x - y} = \frac{x + y}{x} \times \frac{2x}{1} = (x + y) \times 2 = 2x + 2y$

Answer 2

$\displaystyle\bf\\\Big(x-\frac{y^{2} }{x} \Big):\Big(\frac{1}{2} -\frac{y}{2x} \Big)=\frac{x^{2} -y^{2} }{x} :\frac{x-y}{2x} =\frac{(x-y)(x+y)}{x} \cdot\frac{2x}{x-y} =\\\\\\=2\cdot(x+y)=2x+2y$
