Enter an expression equivalent to:

(3x² + 2y² - 3x) + (2x² + y² - 2x) - (x² + 3y² + x)

(3x² + 2y² - 3x) + (2x² + y² - 2x) - (x² + 3y² + x)

**Remove the parentheses, distributing the negative sign, and combine like terms.**

**Like terms have same variables and same exponents.**

(3x² + 2y² - 3x) + (2x² + y² - 2x) - (x² + 3y² + x)

= 3x² + 2y² - 3x + 2x² + y² - 2x - x² - 3y² - x {removed parentheses, distributing signs in front}

=

**4x² - 6x**{combined like terms}
