3n2-8n+4 = (3n-2)(n-2) when factored

3n+2 + (3n+3 - 3n+1) = 3n+1+1 + (3n+1+2 - 3n+1) = 3*3n+1 + (9*3n+1 - 3n+1)= (3+9-1)*3n+1 = 11*3n+1.

Unfortunately, limitations of the browser used by Answers.com means that we cannot see most symbols. It is therefore impossible to give a proper answer to your question. Please resubmit your question spelling out the symbols as "plus", "minus", "equals", "squared", "cubed" etc. Please use "brackets" (or parentheses) because it is impossible to work out whether x plus y squared is x + y2 of (x + y) 2.

It is a algebraic expression which can be simplified depending on the plus or minus values of 3n and 10n which have not been given.

(3n)2 = 9n2

(4n - 1)(3n + 2)

3n + 2 + (3n + 3 - 3n + 1) = 3n + 2 + (3n + 3 - 3n + 1) = 3n + 2 + (4) = 3n + 6

3n+2+3n+2=6n+4

3(3n - 1)(n + 1)

5m+2n, n-3m, 7-3n (5m+2n)+(n-3m)+(7-3n)=2m+7

No. 3n is not a factor of 3n + 7.

The GCF is 3n.

3n2 - 7n = 0 n(3n - 7) = 0 So either n = 0 or 3n-7 = 0 ie, either n = 0 or n = 7/3 = 21/3 = 2.33...

No. 3n is not a factor of 3n + 7.

5n = 2n + 3n .

(9n2 - 121) = (3n + 11) (3n - 11)

is 3n +5 !

6n2 + 16n can be factorised to give 2n(3n + 8) so the highest factor is 2n.

No. 3n isn't a factor of 3n + 7. The GCF of 3n + 7 and 9n is 1.

3n+5n=8n

n2-3n+2

12m + 3n - 6m + 7n6m + 10n

8m + 3n - 5m + 10n = 3m +13n

7n - 2 + 3n + 4 = 7n + 3n - 2 + 4 = 10n + 2 which can be simplified to 2(5n +1)

It's kind of tough to look for the 'answer', because it's not even clear what the question is.All I can think of is: Somebody tells you what 'n' is, and then you're supposed tofigure out what number 5('n' squared + 3n) is. If that's the question, then of courseyou need to know what 'n' is before you can start on it.I'm, not at all sure that that's the question, but it's all I can think of, so here's an example:Let's say that 'n' is 1 .n2 = 13n = 3n2 + 3n = 45('n' squared + 3n) = 54 = 625That may not be too helpful, because, as I said above, the way you postedthe question, I can't see what the 'problem' (the assignment) is.
