Simplifying,Adding,and Subtracting Polynomials
Objective 1: Simplify polynomials in one variable by combing like terms
• To combine like terms :
o Add or subtract the coefficients
o Keep the variables and their exponents the same
• 4x + 9x
•
• 4m + 4m
•
•
•
Objective 2: Add polynomials in one variable
• To add polynomials combine like terms :
o Add or subtract the coefficients
o Keep the variables and their exponents the same
•
•
Objective 3: Write an expression for the perimeter of a given shape
• Remember:
o Perimeter = L + L + W + W
Objective 4: Subtract polynomials in one variable
• To subtract polynomials:
o Change the operation symbol as an equivalent addition statement
▪ Change the operation symbol from a minus sign to a plus
sign
▪ Change all the signs in the second polynomial to their additive inverses
• (2x + 3) – (7x – 2)
