Answer 1

А) 6а^2
б) а^2b+ab^2

Answer 2

Calculation:

To perform the given calculations, let's break down each expression and simplify them step by step.

Expression B: 16a^3 - 2a^2 + 2 + (8a - 3)

1. Combine like terms within the parentheses: 8a - 3 2. Distribute the 16a^3 to each term within the parentheses: 16a^3 - 3(16a^3) = 16a^3 - 48a^2 3. Combine like terms: 16a^3 - 48a^2 + 2 + 8a - 3 = 16a^3 - 48a^2 + 8a - 1

Expression V: 2ab(a + b) - ab(a + b)

1. Combine like terms within the parentheses: a + b 2. Distribute the 2ab to each term within the parentheses: 2ab(a) + 2ab(b) = 2a^2b + 2ab^2 3. Distribute the -ab to each term within the parentheses: -ab(a) - ab(b) = -a^2b - ab^2 4. Combine like terms: 2a^2b + 2ab^2 - a^2b - ab^2 = a^2b + ab^2

Now, let's combine the results of both expressions:

16a^3 - 48a^2 + 8a - 1 + a^2b + ab^2

Therefore, the simplified expression is 16a^3 - 48a^2 + a^2b + 8a + ab^2 - 1.
