n(2n - 1)(2n + 7)
3n + 2n = 7 + 4n 5n = 7 + 4n 5n - 4n = 7 n = 7
If you mean: 4n-2n = 4 then 2n = 4 and n = 2
34 divide by 4n 34 - 4n cause 2nx2 is 2n+2n 2n is n+n so it is n+n+n+n =4n
6n2 + 16n can be factorised to give 2n(3n + 8) so the highest factor is 2n.
n(2n - 1)(2n + 7)
4n
12+4n = 2n12+4n-4n = 2n-4n12 = -2n-1/2(12 = -2n)-6 = n
3n + 2n = 7 + 4n 5n = 7 + 4n 5n - 4n = 7 n = 7
(4n + 1)*(2n + 6) = 8n2 + 26n + 6
3 + 3n = 9 + 2n + 4n n = -2
Move the 2n over the equals sign. Become 4n (as 6n-2n= 4n) and then if 4n=16 then n=4.
4n
-2n
are you sure you don't mean "4n squared - 26n + 42" ?? This would give 2(2n-7)(n-3) Davehx
It can be simplified to: 4m-2n
n= -2
