Polynomials

Because there are different types of polynomials (mono, bi, and poly), and various operations which can be performed on them (+, -, *, /), there are many possible combinations.

Fortunately, there isn't a different rule for every combination. The rules are few, but important. Please write them down when given and keep them neat, organized, and easy to find in your notebook. You will need to be reminded for awhile.

Adding & Subtracting Polynomials

Polynomials

We will look at applying basic addition and subtraction to any type of polynomial. The rule is the same for all types.And it is... Only like terms can be added or subtracted.Example 1: (x + 1) +

(x2 + x) =x2 + 2x + 1

Example 2: (4x4 + 2x + 11) + (-3x2 + x) + (x4 - 2)=

5x4 - 3x2 + 3x +9Example 3: (3x2 - 2x + 10) - (-3x2

+3x + 1) = 6x2 - 5x +9
