1. 6.6 Polynomials with Special Products

2. Polynomial Vocabulary
Standard Form – Largest exponent to smallest exponent
Lead Coefficient – Coefficient of term with largest exponent
Degree – Largest exponent (number of factors (P.4))

3. Addition/Subtraction (answer in standard form)

4. Examples: (9x3 – 2x + 1) + (5x2 + 12x -4) =

5. Multiplication (Distribute)

6. Multiplying Polynomials : Horizontally
(x – 3)(3x2 – 2x – 4)=
3x3 – 2x2 – 4x – 9x2 + 6x + 12=
3x3 – 11x2 + 2x + 12

7. There are formulas (shortcuts) that work for certain polynomial multiplication problems. (a + b)2 = a2 + 2ab + b2 (a - b)2 = a2 – 2ab + b2 (a - b)(a + b) = a2 - b2
Being able to use these formulas will help you in the future when you have to factor. If you do not remember the formulas, you can always multiply using distributive.
