1. Lesson 7.1 Adding and subtracting polynomials
Objective: To add and subtract polynomials
To classify polynomial by degree and by number of terms
EQ: How do you add /subtract polynomials?
Example of a Polynomial
Degrees
Constant
Coefficients

2. Vocabulary Degree: is the exponent for each variable.
Degree of the polynomial: is the largest exponent of the polynomial. (is sum of exponents in same term)
Leading coefficient: is the coefficient of the first term.
Descending order/Standard form is how polynomials are written where the terms are placed in descending order from largest degree to smallest.

3. Example: Write the polynomials in Standard form/descending order
Example: Write the polynomials in Standard form/descending order. Then identify the leading coefficient and degree of the polynomial. 1.
Degree is 7
Leading coefficient is 3 2.
Degree is 4
leading coefficient is –2 3.

4. Classifying Polynomials By Degree Degree Example
Constant 6 -3
Linear 1
3x + 4
-7x + 2
Quadratic 2
Cubic 3
Quartic 4

5. Classifying polynomials By # of terms # of terms Example
Monomial 1 3x
Binomial 2
3x + 1
Trinomial 3
Note: Any polynomials with four or more terms are just called polynomials
