Adding and Subtracting polynomials

Slide 2: 

Remember to add or subtract “like terms”. Like terms have the same variable and the same corresponding exponents. 1. (4x2 – 3x + 6) + (2x2 – 4x – 1) = 6x2 Add the 4x2 and 2x2. -7x Add -3x and -4x. +5 Add the 6 and -1.

Slide 3: 

2. (5x3 – 7x + 1) – (2x3 – 6x2 – 8x – 1) Subtract 5x3 and 2x3. Subtract 0 and -6x2. Subtract -7x and -8x. Subtract 1 and -1. 3x3 +6x2 +x +2
