Question 767844: how do you find the missing polynomials
EX. (4x^2-3x+2)-(x^2+x+2)+( _ _ _ _ ) = 5x^2+3x-2
Answer by algebrahouse.com(1659)   (Show Source):
You can put this solution on YOUR website! (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}
