Answer 2

It looks like you have an algebraic expression:

(х + 5) * 4х - (2х + 5)^2

To simplify this expression, you can follow these steps:

1. Distribute the 4х on the left side of the expression:

4х(х + 5) - (2х + 5)^2

2. Expand (2х + 5)^2:

4х(х + 5) - (4х^2 + 20х + 25)

3. Distribute the 4х into the terms inside the parentheses on the left side:

4х^2 + 20х - (4х^2 + 20х + 25)

4. Now, distribute the negative sign to all terms inside the parentheses on the right side:

4х^2 + 20х - 4х^2 - 20х - 25

5. Notice that the terms "4х^2" and "-4х^2" cancel each other out, as do the terms "20х" and "-20х":

(4х^2 - 4х^2) + (20х - 20х) - 25

6. After canceling out those terms, you're left with:

-25

So, the simplified expression is:

-25
