1) Factor out the GCF: 6xy - 9yz + 15xz
GCF is 3
Factor form: 3(2xy-3yz+5xa)
-------------
2) Factor by grouping: 2x^2 + 10x - 3x - 15
2x(x+5)-3(x+5)
(x+5)(2x-3)
-----------------
3) Factor completely: 3a^2 - 27b^2
3(a^2-9b^2
=3(a-3b)(a+3b)
-------------------
4) Factor completely: 15x^2 + 7x - 2
(5x-1)(3x+2)
---------------
5) Factor completely: 9a^2 - 24ab + 16b^2
(3a-4b)(3a-4b)
=(3a-4b)^2
--------------------
