6n
6n(2n - 3)
6n+3=15 6n+3-3=15-3=12 6n = 12 n=12/6 = 2
6n - 4 - 3 = 3n + 10 + 4n -7 = 7n - 6n + 10 -17 = n
Move the 2n over the equals sign. Become 4n (as 6n-2n= 4n) and then if 4n=16 then n=4.
6n2 + 16n can be factorised to give 2n(3n + 8) so the highest factor is 2n.
6n = 12 n = 2
6n
m2 - 4mn - 12n2 = m2 - 6mn + 2mn - 12n2 = m(m - 6n) + 2n(m - 6n) = (m + 2n)(m - 6n)
6n(2n - 3)
7n + 1 = 6n + 8 7n=6n+7 (minus 1 from each side) n=7 (7n-6n equals n, you are left with n=7)
-5=6n+7 -5-7=6n+7-7 -12=6n -12/6=6n/6 -2=n
6n+3=15 6n+3-3=15-3=12 6n = 12 n=12/6 = 2
7n3 + 6n = n*(7n2 + 6)
6n - 4 - 3 = 3n + 10 + 4n -7 = 7n - 6n + 10 -17 = n
The GCF is 6.
Move the 2n over the equals sign. Become 4n (as 6n-2n= 4n) and then if 4n=16 then n=4.
