Find the difference between (5x² + 10x - 5) and (4x² - 6x + 1)?
Put a minus sign between them keeping them in parentheses:

(5x² + 10x - 5) - (4x² - 6x + 1)

Remove parentheses.  The second parentheses is preceded by a -,
so change the signs of all terms inside when removing parentheses:

5x² + 10x - 5 - 4x² + 6x - 1

Combine like terms 5x² and -4x² as 1x² or x².
Combine like terms 10x and 6x as 16x.
Combine like terms -5 and -1 as -6.

x² + 16x - 6.
