Question

(a+1)²-2(a+1)+1= Упростить

Answer 1

Ответ:

а²

Объяснение:

1)(а+1)²=а²+2а+1

2)-2*(а+1)=-2а-2

3)а²+2а+1-2а-2+1=а²

Answer 2

Ответ:

а^2

Объяснение:(а+1)^2-2(a-1)+1=а^2+2a+1-2a-2+1=a^2

Answer 3

To simplify the expression (a+1)² - 2(a+1) + 1, follow these steps:

Step 1: Expand the squared term (a+1)² Step 2: Distribute the -2 to the terms inside the parentheses Step 3: Combine like terms

Let's do it:

Step 1: (a+1)² = (a+1) * (a+1) = a * a + 2 * a * 1 + 1 * 1 = a² + 2a + 1

Step 2: -2(a+1) = -2 * a - 2 * 1 = -2a - 2

Now, let's put everything back together:

(a+1)² - 2(a+1) + 1 = (a² + 2a + 1) - (2a + 2) + 1

Step 3: Now, combine the like terms: = a² + 2a + 1 - 2a - 2 + 1

Combine the constants: = a² + 1 - 2

Finally, the simplified expression is: a² - 1
