How do i factor the "common factor out of each expression?" ex:

12n^6 + 27n^2 - 18

whoever answers correct / first ill give brainliest

Step-by-step explanation:

A "common factor" is either a constant coefficient or a variable which shows up in every term of a given algebraic expression.

Here we start with the expression 12n^6 + 27n^2 - 18. 'n' does not show up in every term and thus could not be a "common factor" of this expression. On the other hand, 12, 27 and - 18 can all be divided by 3, and so 3 is a common factor.

12n^6 + 27n^2 - 18 = 3 (4n^6 + 9n^2 - 6)

1) Identify the common factor (here it's 3)

2) Factor that out of the given expression: 3 (4n^6 + 9n^2 - 6)
