Упростим выражение  25a^3 - (1 + 5a)(5a^2 - a) и найдем его значение при заданном значении переменной а = - 11,4.

Для открытия скобок будем использовать правило открытия скобок перед которыми стоит знак минус и правило умножения скобки на скобку.

25a^3 - (1 + 5a)(5a^2 - a) = 25a^3 - (1 * 5a^2 - 1 * a + 5a * 5a^2 + 5a * (- a)) = 25a^3 - 5a^2 + a - 25a^3 + 5a^2;

Сгруппируем и приведем подобные слагаемые.

25a^3 - 5a^2 + a - 25a^3 + 5a^2 = 25a^3 - 25a^3 - 5a^2 + 5a^2 + a = a.

При а = - 11,4.

а = - 11,4.

ответ: а = - 11,4.
