Do you know how to use calculator to find fast answer?
1) press mode 3 times
2)then u find 'EQN'then press 1
3)then u can see 'UNKNOWS'but dont use the 'UNKWOWS' you must press to tge right i u can see 'DEGREE' then if you already find the DEGREE you press number 2
4)Then the 'a?' will out u can put 1 stand for X^2 then equal
5) next the 'b?' come out you put 6 stand for 6x then equal
6)final the 'c?'will come out and you put -27 then equal
7) then the answer will come out
it will be x1=3 and x2=-9
8) but if you want to put in bracket the x1=will be -3 and the x2= will be 9
so final answer
(x-3)(x+9)

The Greatest Common Factor (GCF) is very important when factoring. Later on, you will forget to pull out a GCF and the answer will be wrong. Always look for a GCF before doing anything.
Let's try factoring these:
a.)
The greatest common factor of this expression is 9, because it is the maximum number that both can go into. Let's solve.
This is the simplest this expression can get. This would be your final answer. Let's try the other one.
b.)
The GCF of this one is 12. Let's simplify it.
This is also the simplest you can get it. You can do nothing further. So, your final answers are:
a.)
b.)
