Answer 2

Пошаговое объяснение:

1)(а+b) 2

2)(a-b) 2

3)(x-5)2

Answer 3

1. The expression "a² + b² + 2ab" represents the square of the sum of "a" and "b". It can be simplified using the identity (a + b)² = a² + 2ab + b². So, we have:

a² + b² + 2ab = (a + b)²

2. The expression "a² + b² - 2ab" represents the square of the difference between "a" and "b". It can be simplified using the identity (a - b)² = a² - 2ab + b². So, we have:

a² + b² - 2ab = (a - b)²

3. The expression "x² - 10x + 25" is a quadratic trinomial. It can be factored as a perfect square trinomial because the first and last terms are perfect squares. The perfect square trinomial (a - b)² can be expressed as a² - 2ab + b². In this case, we have:

x² - 10x + 25 = (x - 5)²

Therefore, the simplified forms of the given expressions are:

1. a² + b² + 2ab = (a + b)²
2. a² + b² - 2ab = (a - b)²
3. x² - 10x + 25 = (x - 5)²
