Answer:
- 6(x^2 +18z +81) . . . as written
- 6(x +9)^2 . . . . . . . . assuming a typo
Step-by-step 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)
__
<em>Assuming a typo in the question</em>
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).
He would have to wash 20 cars at first i got 19.25 because i divided 231 by 12 but i rounded up to 20 just to be safe....
To factor polynomials, find a common number to remove and leave the rest in parentheses. I did the odds, now you try the evens. If you still need help,, let me know.
1. 3 (x+4)
3. 5 (x+6y)
5. 3(2 a^2 + 9)
7. 3d (7c -1)
9. 15a (ab - 2b)
