Question

25а² + 10аb + b2 25a² - 10ab +b²​

Answer 1

1/ (5а+b)²

2/ (5a-b)²

Answer 2

25а² + 10аb + b² =

(5a + b)²

25a² - 10ab +b² =

(5a - b)²

Answer 3

The expression you've provided appears to be a difference of squares, which can be factored using the following formula:

a^2 - b^2 = (a + b)(a - b)

In your case, the expression is:

25a² + 10ab + b² - 25a² + 10ab - b²

Notice that the first two terms are the same as the last two terms, but with opposite signs. We can group them as follows:

(25a² - 25a²) + (10ab + 10ab) + (b² - b²)

The first and third groups are the difference of squares, so they simplify to zero:

0 + 20ab + 0

Thus, the simplified expression is:

20ab
