9m2+ 9mn- 4n2
2mn + 4n2 and 5m2 - 7mn
4n2 + 5m2 - 5mn
If you mean: 4n^2+62n-32 then it is (2n-1)(n+16) when factored after dividing all terms by 2
8n + 4n2 -8n
sqrt(4n2) = 2n
9m2+ 9mn- 4n2
2mn + 4n2 and 5m2 - 7mn
4n2 + 5m2 - 5mn
4n2 is one expression. You need at least two to find a GCF
If you mean: 4n^2+62n-32 then it is (2n-1)(n+16) when factored after dividing all terms by 2
4n2
4n2-25 = 0 4n2=25 n2=6.25 n=sqrt(6.25) n= +2.5 or -2.5
2n/3
8n + 4n2 -8n
The expression is 36n^2 - 81.
