Question

0,1х²-0,02у²-0,17х²+0,08у²​

Answer 1

Объяснение:

$0,1x {}^{2} - 0,02y {}^{2} - 0,17x {}^{2} + 0,08y {}^{2} \\ \\ \frac{1}{10} x {}^{2} - \frac{1}{50} y {}^{2} - \frac{17}{100}x {}^{2} + \frac{2}{25} y {}^{2} \\ \\ \frac{1}{100} \times (10x {}^{2} - 2y {}^{2} - 17x {}^{2} + 8y {}^{2} ) \\ \\ \frac{1}{100} \times ( - 7x {}^{2} + 6y {}^{2} )$
