General Trinomial (Perfecy Square Trinomial) |
*recognize*
-3 terms
-1st and last terms are perfect sqares
-middle term is twice the product of the roots
ex.
x+6x+9
(x+3)(x+3)
(x+3)
ex.
4x+12xy+9y
(2x)+12xy+(3y)
(2x+3y)

Grouping |
-4 terms
1)Group 1st two terms; group last two terms
2)For each group, pull out GCF
3)CLT (Combine Like Terms)
ex. 20x 5x 32x 8
(20x 5x) (32x 8)
5x(4x 1) 8(4x 1)
(5x 8)(4x 1)

General Trinomial (a=1) |
-Look for 2 numbers (p & q), that multiply to c and add to d. (pq=c and p+q=d)
(a)x+bx+c => (x+p)(x+q)
ex. x+17x+42 => (x+14)(x+3)
x-19x+60 => (x-15)(x-4)

GCF (Greatest Common Factor) |
GCF
Step 1: *Always look for a GCF ( Greatest Common Factor)*
15xyz-20xyz+25xyz=
5xyz(3xy-4x+5y)
