Question 767844
(4x² - 3x + 2) - (x² + x + 2) + (_ _ _ _) = 5x² + 3x - 2
4x² - 3x + 2 - x² + x - 2 + (_ _ _ _) = 5x² + 3x - 2 {took out parentheses, distributing negative sign}
3x² - 2x + (_ _ _ _) = 5x² + 3x - 2 {combined like terms}


To find what you add to 3x² - 2x to get 5x² + 3x - 2, subtract.


(5x² + 3x - 2) - (3x² - 2x) {subtracted}
= 5x² + 3x - 2 - 3x² + 2x {took out parentheses, distributing negative sign}
= 2x² + 5x - 2 {combined like terms}
