Answer 2

Let's simplify the equation step by step:

Starting with the left side of the equation:

3x² - 3x + 1 - (2x² + 3x + 1) - (x² - 5x)

Distribute the negative sign inside the parentheses:

3x² - 3x + 1 - 2x² - 3x - 1 - x² + 5x

Combine like terms:

(3x² - 2x² - x²) + (-3x - 3x + 5x) + (1 - 1)

Simplify further:

(3 - 2 - 1)x² + (-3 - 3 + 5)x + (1 - 1)

x² - x + 0

Now, we have simplified the equation to:

x² - x = -4
