Answer 1

Ответ:

нужно решать их на эту формулу:

(a+b)³=a³+3a²b+3ab²+b³

(a-b)³=a³-3a²b+3ab²-b³

только наоборот

Answer 2

(a+b)3=a3+3ab+3ab2+b3

(a-b)3=a3-3ab+3ab2-b3
ну походу так

Answer 3

It seems like you have provided a list of mathematical expressions. Let's go through each one and simplify them where possible.

1. 3x - 6x² - 10xy + 5y: This expression cannot be simplified further. It is already in its simplest form.

2. 21y + 6xy - 10x - 35: This expression cannot be simplified further. It is already in its simplest form.

3. 35ab - 42ac + 20b - 24c: We can factor out common terms: 35ab - 42ac + 20b - 24c = (35ab + 20b) - (42ac + 24c) Now, we can factor out '5b' and '6c' respectively: (35ab + 20b) - (42ac + 24c) = 5b(7a + 4) - 6c(7a + 4) Therefore, the simplified expression is 5b(7a + 4) - 6c(7a + 4).

4. 21x² + 4x - 28: This expression cannot be simplified further. It is already in its simplest form.

5. 3x³y³ + 11y² + 5y + 55: This expression cannot be simplified further. It is already in its simplest form.

6. 4x³48x² + 5x - 60: It seems there is a missing operator between '4x³' and '48x²'. If we assume it is a multiplication, then the expression becomes: 4x³ * 48x² + 5x - 60. We can simplify this expression by multiplying the coefficients: 4 * 48 = 192. The simplified expression is 192x^5 + 5x - 60.

Please double-check the expressions provided and ensure they are correctly formatted. If you have any further questions, feel free to ask!
