Question

9 9 5) (2,5xy +1,25m) + (1,25m + 2,5xy)y-(1,25m + 2,5xy)x. ​

Answer 1

Ответ:

$(2,5xy +1,25m) + (1,25m + 2,5xy)y-(1,25m + 2,5xy)x.$

$\frac{5m}{4} + \frac{5xy}{2} - x( \frac{5m}{4} + \frac{5xy}{2} ) + y ( \frac{5m}{4} + \frac{5xy}{2} )$

$\frac{5m}{4} + \frac{5xy}{2} - \frac{5x(m + 2xy)}{4} + y( \frac{5m}{4} + \frac{5xy}{2} )$
