This mathematics class document discusses operations with polynomials. It explains how to perform addition and subtraction of polynomials by combining like terms. For addition, polynomials are combined by grouping like terms. For subtraction, the operation is written as an equivalent addition problem by changing the subtraction sign to addition and switching the signs of the terms in the number being subtracted. Examples are provided to demonstrate both addition and subtraction of polynomials.

POLYNOMIALS I
•In this lesson, you will be able
to…
⮚ Perform the fundamental

+ 8x + 9
+ 8x + 9
Note: Combining like terms is
more applicable as the
polynomials get more
complex than using stacking
method.

5. Subtracting Polynomials
⮚ To subtract polynomials, do the following procedures:
1. Write the subtraction statement as an equivalent addition statement.
a. Change the operation symbol from a minus sign to a plus sign.
b. Change the sign of each term of the subtrahend.
2. Combine like terms
Solution: Write an equivalent addition statement.
Change the
minus sign to
plus sign
Change all
signs in the
subtrahend
Combining like terms

6. Solution: Write an equivalent addition statement.
