Question

а(а+2b)-(b+a) во 2 степениупроститее

Answer 1

(а2+2ab)-(b2+2ab+a2)= a2+2ab-b2-2ab-a2= -b2

Answer 2

a(a-2b)-(b+a)2= a2 - 2ab - b2-2ab-a2=  -4ab -b2

(a2 и -a2 сокращаем)

Answer 3

Simplifying the Expression

To simplify the expression (a+2b)-(b+a)+2, we can start by combining like terms.

The expression can be simplified as follows: (a+2b)-(b+a)+2 = a + 2b - b - a + 2

Now, let's simplify the expression step by step.

1. Combine like terms: a - a + 2b - b + 2 = 2b - b + 2

2. Further simplify: 2b - b + 2 = b + 2

So, the simplified form of the expression (a+2b)-(b+a)+2 is b + 2.

This simplification is based on the basic principles of combining like terms and simplifying expressions.
