Answer:
- 6(x^2 +18z +81) . . . as written
- 6(x +9)^2 . . . . . . . . assuming a typo
Explanation:
As the expression is written, the only factoring that can be done is to factor out the common numeric factor of 6:
= 6(x^2 +18z +81)
__
Assuming a typo in the question
If we assume all variables are supposed to be "x", then the quadratic term can be further factored as a square:
= 6(x +9)^2
_____
It is often handy to remember that the form of the square of a binomial is ...
(a +b)^2 = a^2 +2ab +b^2
Here, we recognize that 18 = 2√81, so the binomial is (x +√81) = (x +9).
