Question

2 2. 2 3 1)(a+3) +(a-3)=? 2)(1-а) (1+а+а )+а Помагите решить

Answer 1

Отсвет будет а^2 и все. Это можно сделать логично

Answer 2

1) (a+3) +(a-3) =2(а+3)=2а+6
2) (1-а) (1+а+а )+а=1+а+а-а-аа-аа+а=1+а+2аа
если вы проходили степень то вместо аа будет а^2

Answer 3

Solution to the Equations

To solve the given equations, let's break them down step by step:

1) (a+3) + (a-3) = ?

To simplify this equation, we can combine like terms:

(a + 3) + (a - 3) = 2a + 0 = 2a 2) (1-а) + (1+а+а+)а = ?

Again, let's combine like terms:

(1 - а) + (1 + а + а +)а = 1 - а + 1 + а + а + а = 2 + 3а = 3а + 2 Therefore, the simplified equations are: 1) (a+3) + (a-3) = 2a 2) (1-а) + (1+а+а+)а = 3а + 2
