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
Polynomials are classified by their quot;degreesquot;
The degree of a polynomial is the HIGHEST exponent
What do you notice about the exponets in the above example?
When writing a poynomial in standard form--the term witht he
HIGHEST exponent goes first and the rest are in descending order.
Some polynomials have special names---make sure you can recognize
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.
Adding Polynomials is not that hard----
-Just remember--you are doing NOTHING with the exponents
except using them to match up.
Adding Polynomials helps you to solve more complicated
problems involving geometry concepts--
THINK about what it is asking you and APPLY the concept....
Try this.... pg. 429 (top)
What method do you use?????
Subtracting Polynomials is just as easy...
BUT- do not forget your KEEP, CHANGE, CHANGE!
Watch your subtraction signs......
