Slide 2:
Objectives: At the end of 45-minute session, the students will be able to: a. demonstrates that factoring polynomial having common factors is the inverse process of multiplying a polynomial by a monomial; b. find the greatest common factor; and c. participate in class activities.
Slide 3:
Factor -portion of a quantity, usually an integer or polynomial that, when multiplied by other factors, gives the entire quantity Product - the result of multiplying, or an expression that identifies factors to be multiplied. Distributive Law - one of the basic laws of algebra, says: a(b+c)=ab+ac. This is handy for simplifying, by getting rid of parentheses. Factoring an expression like ab+ac=a(b+c) is the distributive law backwards. It too can help to simplify, as maybe the a or b+c can be divided out of a bigger equation somehow.
Slide 4:
4a(3a-4b) What are the factors? What is the product? 12a2 - 16ab
Slide 5:
Examples: 2a (m+5n)=
3x (2x-1)=
3. a2 (a2+b2)= 2am + 10an 6x2 - 3x a4 + a2b2 Product Greatest common factor 2a 3x a2
Slide 6:
What is the greatest common factor ? axy + az
6m + 6n
4a2 + 12a What is the product?
Slide 7:
Board work: By Group. (5 Members each group)
Each member will given a chance to write on the board.
Define the greatest common factor and the product of each polynomial
12xy2 + 6x =
3xy – 6xy +9y=
4a – 16ab=
12abc – 4ac – 3ab=
16bc + 16abc
Slide 8:
Assignment: ¼ sheet of paper.
Find the greatest common factor of the following
9y + 18y
7x + 21x
10xyz - 110xyz
-12ab +120ab
24x – 48xy
