(2n-6)^3

Answer 1

is it 8n^2-216?

Answer 2

lols..how wood i noe? im asking it! i jus needa know how to do it :D

Answer 3

lol idk!!

Answer 4

(-6+2 n)^3
= (-6+2 n) (-6+2 n)^2
= -6 (-6+2 n)^2+2 n (-6+2 n)^2
= -6 (-6+2 n)^2+2 n (-6+2 n) (-6+2 n)
= -6 (-6+2 n)^2+2 n (-6 (-6+2 n)+2 n (-6+2 n))
= -6 (-6+2 n)^2+2 (n (-6) (-6+2 n)+n 2 n (-6+2 n))
= -6 (-6+2 n)^2+2 (-6 n (-6+2 n)+2 n n (-6+2 n))
= -6 (-6+2 n)^2+2 (-6 (n (-6)+n 2 n)+2 n (n (-6)+n 2 n))
= -6 (-6+2 n)^2+2 (-6 (-6 n+2 n n)+2 n (-6 n+2 n n))
= -6 (-6+2 n)^2+2 (-6 (-6 n+2 n n)+2 (n (-6) n+n 2 n n))
= -6 (-6+2 n)^2+2 (-6 (-6 n+2 n n)+2 (-6 n n+2 n n n))
= -6 (-6+2 n)^2+2 (-6) (-6 n+2 n n)+2 2 (-6 n n+2 n n n)
= -6 (-6+2 n)^2-6 2 (-6 n+2 n n)+2 2 (-6 n n+2 n n n)
= -6 (-6+2 n)^2-6 2 (-6) n-6 2 2 n n+2 2 (-6) n n+2 2 2 n n n
= -6 (-6+2 n)^2-6 (-6) 2 n-6 2 2 n n-6 2 2 n n+2 2 2 n n n
= -6 (-6+2 n)^2-6 (-6) 2 n+2 (-6) 2 2 n n+2 2 2 n n n
= -6 (-6+2 n)^2-6 (-6) 2 n-6 2 2 2 n n+2 2 2 n n n
= -6 (-6+2 n) (-6+2 n)-6 (-6) 2 n-6 2 2 2 n n+2 2 2 n n n
= -6 (-6 (-6+2 n)+2 n (-6+2 n))-6 (-6) 2 n-6 2 2 2 n n+2 2 2 n n n
= -6 (-6 (-6+2 n)+2 (n (-6)+n 2 n))-6 (-6) 2 n-6 2 2 2 n n+2 2 2 n n n
= -6 (-6 (-6+2 n)+2 (-6 n+2 n n))-6 (-6) 2 n-6 2 2 2 n n+2 2 2 n n n
= -6 (-6) (-6+2 n)-6 2 (-6 n+2 n n)-6 (-6) 2 n-6 2 2 2 n n+2 2 2 n n n
= -6 (-6) (-6)-6 (-6) 2 n-6 2 (-6) n-6 2 2 n n-6 (-6) 2 n-6 2 2 2 n n+2 2 2 n n n
= -6 (-6) (-6)-6 (-6) 2 n-6 (-6) 2 n-6 2 2 n n-6 (-6) 2 n-6 2 2 2 n n+2 2 2 n n n
= -6 (-6) (-6)+3 (-6) (-6) 2 n-6 2 2 n n-6 2 2 2 n n+2 2 2 n n n
= -6 (-6) (-6)-6 (-6) 2 3 n-6 2 2 n n-6 2 2 2 n n+2 2 2 n n n
= (-6)^(1+1+1)+(-6)^(1+1) 2 3 n-6 2^(1+1) n^(1+1)-6 2^(1+1+1) n^(1+1)+2^(1+1+1) n^(1+1+1)
= (-6)^(1+1+1)+2 3 (-6)^(1+1) n-6 2^(1+1) n^(1+1)-6 2^(1+1+1) n^(1+1)+2^(1+1+1) n^(1+1+1)
= -216+2 3 36 n-6 4 n^2-6 8 n^2+8 n^3
= -216+6 36 n-24 n^2-48 n^2+8 n^3
= -216+216 n-24 n^2-48 n^2+8 n^3
= 8 n^3-72 n^2+216 n-216

Answer 5

Hope u got it now :):)):):):):)

Answer 6

that was way over how i solved.....
