ЛЮДИ ПОМОГИТЕ ТОЛЬКО ПРАВИЛЬНО

Answer 1

$\frac{x^2}{(x-y)(x+y)} \Leftrightarrow \frac{x-y}{6(x+y)};\\\frac{6x^2}{6(x^2-y^2)} \Leftrightarrow \frac{(x-y)^2}{6(x^2-y^2)};\\\frac{6x^2}{6(x^2-y^2)} \Leftrightarrow \frac{x^2-2xy+y^2}{6(x^2-y^2)};$

Answer 2

$1)\frac{x^{2}} {x^{2}-y^{2}}= \frac{x^{2}} {(x-y)(x+y)}= \frac{6x^{2}} {6(x+y)(x-y)}=\frac{6x^{2}} {6(x^{2}- y^{2})}} \\\2) \frac{x-y}{6x+6y}= \frac{x-y}{6(x+y)}= \frac{(x-y)(x-y)}{6(x+y)(x-y)}= \frac{(x-y)^{2}} {6(x^{2}-y^{2})}= \frac{x^{2}-2xy+y^{2}}{6(x^{2}-y^{2})}$
