### 9.1 Adding And Subtracting Polynomials

1. 1. Algebra Warm Up: pg. 431 # 55 to 59
2. 2. 9.1 Adding and Subtracting Polynomials pg. 426 to 431 Recall that a monomial is.... ONE thing A Polynomial is monomials separated by + or - signs
3. 3. Polynomials are classified by their quot;degreesquot; The degree of a polynomial is the HIGHEST exponent ex. What do you notice about the exponets in the above example?
4. 4. When writing a poynomial in standard form--the term witht he HIGHEST exponent goes first and the rest are in descending order. ex. Some polynomials have special names---make sure you can recognize them.
5. 5. Adding Polynomials is really easy.... --Just add the coefficients of the like terms --DO NOTHING with the exponents--they are only there for you to match the terms together.
6. 6. Adding Polynomials is not that hard---- -Just remember--you are doing NOTHING with the exponents except using them to match up.
7. 7. Adding Polynomials helps you to solve more complicated problems involving geometry concepts-- THINK about what it is asking you and APPLY the concept....
8. 8. Try this.... pg. 429 (top) What method do you use?????
9. 9. Subtracting Polynomials is just as easy... BUT- do not forget your KEEP, CHANGE, CHANGE!
10. 10. Watch your subtraction signs...... Try this middle pg. 429
11. 11. Try some more...pg. 430 # 6-16
