Answer 1

Ответ:

$\frac{ {a}^{3} + 216 }{2a + 12} = \frac{ {a}^{3} + {6}^{3} }{2(a + 6)} = \frac{(a + 6)( {a}^{2} - 6a + 36) }{2(a + 6) } = \frac{ {a}^{2} - 6a + 36}{2}$

Объяснение:

а³+b³=(a+b) (a²-ab+b²)

Answer 2

To simplify the expression A^3 + 216/(2a) + 12, we need to find a common denominator for the fractions and combine the terms.

First, let's simplify 216/(2a):

216/(2a) = 108/a

Now the expression becomes:

A^3 + 108/a + 12

The terms are unlike, so we cannot combine them further without additional information about the variable 'A'. If there's more context or specific instructions related to 'A', please provide them, and I'll be happy to assist you further.
