СОКРАЩЕНИЕ АЛГЕБРАИЧЕСКИХ ДРОБЕЙ С 1 ПО 6 ПРИМЕРЫ...

polinazubareva1 1. (х-у)(х+у)/х-у = х+у
2. а+в/(а+в)(а-в) = 1/а-в
3. (с-т)(с+т)/4(с+т) = с-т/4
4. 2(а-1)(а+1)/3(а+1) = 2(а-1)/3
5. х во второй*(1-4а)/(1-4а)(1+4а) = х во втрой/ 1+4а
6. (2х-3х)(2х+3х)/2(2х+3х) = 2х-3х / 2
7. 5х(1+3х)/(1-3х)(1+3х) = 5х/ 1 - 3х
8. (х-у)(х+у)/без изменений = х+у/х-у
