Раскрытие скобок

by Учитель
1

Если перед скобками ставится знак «минус», то знаки членов, заключаемых в скобки, записывают с теми же знаками;

2

Произведение любых двух многочленов можно представить в виде одночлена;

3

Буквенный множитель одночлена, записанного в стандартном виде, называется коэффициентом одночлена;

4

Если левая и правая часть равенства тождественно равны одному и тому же выражению, то исходное равенство – тождество;

5

При умножении многочлена на многочлен каждый член одного многочлена умножается на каждый член другого многочлена;

6

Алгебраическая сумма нескольких одночленов является одночленом;

7

Если перед скобками ставится знак «плюс», то члены, которые заключают в скобки, записываются с теми же знаками.
