Question

7,1x²-7,1y² 6а помощь ​

Answer 1

Ответ:

разложение на множники

$7. {1x}^{2} - 7. {1y}^{2} 6a \\ \frac{71}{10} {x}^{2} - \frac{71}{10} {y}^{2} \times 6 \\ \frac{71}{10} \times ( {x}^{2} - {y}^{2} \times 6) \\ \frac{71}{10} \times ( {x}^{2} - 6 {y}^{2} )$

и упрощение

$7. {1}^{2} - 7. {1}^{2} \times 6 \\ 7. {1x}^{2} - (7.1 \times 6) {y}^{2} \\ {7.1x}^{2} - {42.6y}^{2}$
