Answer 1

Упрощаем выражение,получается 
-5х+5=х(х-1) 
-5x+5 =x(x - 1)
Получается -5

Answer 2

Solving the Equation x^2 - 5x + 5 = -x^2 - x - (-3 - 2x^2)

To solve the equation x^2 - 5x + 5 = -x^2 - x - (-3 - 2x^2), we'll follow these steps:

1. Combine like terms on both sides of the equation. 2. Simplify the equation to isolate the variable x. 3. Solve for x.

Step 1: Combine Like Terms

First, let's combine like terms on both sides of the equation:

x^2 - 5x + 5 = -x^2 - x - (-3 - 2x^2)

This simplifies to:

2x^2 - 4x + 5 = 3 + 2x^2

Step 2: Simplify the Equation

Now, let's simplify the equation further to isolate the variable x:

2x^2 - 4x + 5 = 3 + 2x^2

Subtract 2x^2 from both sides:

-4x + 5 = 3

Subtract 3 from both sides:

-4x + 2 = 0

Step 3: Solve for x

Finally, let's solve for x:

Add 4x to both sides:

5 = 4x + 2

Subtract 2 from both sides:

3 = 4x

Divide by 4:

x = 3/4

So, the solution to the equation x^2 - 5x + 5 = -x^2 - x - (-3 - 2x^2) is x = 3/4.
