Question

(2+а ).12а+8 а+1). 3а+3а

Answer 1

Ответ:

(2+а)=

а= - 2

12а+8=

12а= - 8

а= - 8/12= - 2/3= - 0,6

а+1=

а = - 1

3а+3а=6а

Answer 2

It seems like you're trying to simplify the expression $(2+a)\cdot 12a + 8a + 1\cdot (3a + 3a)$. Let's break it down step by step and simplify the expression:

1. Expand the terms inside the parentheses: $(2 + a) \cdot 12a + 8a + (3a + 3a)$ $= 24a + 12a^2 + 8a + 6a$

2. Combine like terms: $= (24a + 8a + 6a) + 12a^2$ $= 38a + 12a^2$

So, the simplified expression is $38a + 12a^2$.
