Subject/Grade Level/Date
MATHEMATICS 8
AUGUST 29-30
Competency (MELCs):
Objectives:
The learners factor completely different types of polynomials
(polynomials with common monomial factor, difference of
two squares, sum and difference of two cubes, perfect
square trinomials, and general trinomials).
1. Find the GCF of the numbers
2. Factor polynomials using common monomial factor.
3. Appreciate the concept about factoring out the common
factor in
polynomials.
Subject Matter:
Factoring Polynomials using common monomial factor
Activities:
Factoring the common monomial factor is the reverse process
of monomial to polynomials.
a(b + c) = ab + ac
a. Factor xy + xz
Get the CMF, x
Divide xy + xz by x
Quotient: y + z
Thus xy + xz = ( y + z)
b. Factor 5n² + 15n
Get the CMF, 5n
Divide 5n² = 15 n by 5n
Quotient: n + 3
Thus 5n² + 15n = 5n (n + 3)
c. Factor 27y² + 9y -18
The CMF is 9
Divide 27y² + 9y -18 by 9
The quotient is 3y² + y -2
Thus 27y² + 9y -18 = 9 ( 3y² + y -2)
