Adding & Subtracting Polynomials By Chad Rosevear & Kade Britton!!!!!! First, you need to know some vocab words like terms Like terms Like terms are terms whose variables are the same. 7x x -2x 3.14x Important Formulas and Concepts: Adding Polynomials Let's try it add 2x + 6x + 5 and 3x - 2x - 1 Start with: 2x + 6x + 5 + 3x - 2x - 1

Place like terms together: 2x + 3x + 6x - 2x + 5 - 1

Add the like terms: (2+3)x + (6-2)x + (5-1) = 5x + 4x + 4 2 2 2 2 2 2 an x and an x are not the same thing, this is not a like term 2 2 2 2 Horizontal Method Vertical Method 2x + 6x + 5 + 3x - 2x - 1 2x + 6x + 5

3x - 2x - 1 5x + 4x + 4 2 2 2 2 2 add subtracting polynomials vertical method To subtract Polynomials, first reverse the sign of each term you are subtracting (in other words turn "+" into "-", and "-" into "+"), then add as usual. 2x + 6x + 5 - 3x - 2x - 1 2 2 2x + 6x + 5 3x + 2x + 1 2 2 remember to change the second group of numbers signs to the opposite of what it was

(+ to _ & - to +) - -1x + 4x + 4 Thanks for watchin!!!!!!! Now here's your quiz haha quiz 1 1. (2pts) what do diferent you do when using the vertical metod when subtracting 2. (3pts) what is 3x-2x - 4x + 4x-3x-5x 2 2 3. (4pts) describe step by step how to subtracrt polynomials with either method.
