a) by using GCF

b) by grouping

By using GCF:

Simply find the GCF

ex:

a) 8x+24

8(x+3)

Since 8 is the GCF of this you divide each term by the GCF which is 8.

b) 2x(a+b)-y(a+b)

(2x-y)(a+b)

Since (a+b) is common on the two terms. You combine them as one. Then combining the term outside of each parenthesis.

By grouping

ex:

a) ac+ad+bc+bd

(ac+ad)+(bc+bd)

a(c+d)+b(c+d)

(a+b)(c+d) or (c+d)(a+b) either way it's the same

Group the term with each something common in it. Like, (ac+ad) a is the common thing. Then start doing GCF.

See the pattern? Factoring is easy, you just need a lot of practice.
