Answer 1

Ответ:

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

$2) \frac{4 {x}^{2}y }{12xy} = \frac{x}{3}$

$3) \frac{64 - {x}^{2} }{3 {x}^{2} - 24x } = \frac{ (4 - x)(4 + x) }{ - 3x(4 - x)} = - \frac{4 + x}{ 3x}$

$4) \frac{4 {x}^{2} - 4x }{3x - 3} = \frac{4x(x - 1)}{3(x - 1)} = \frac{4x}{3}$
