Sorry had a long day... just need this checking over please
(3n+2)(3m+2)(3p+2) = 27nmp + 6(m+n+p) + 8 :zzz:
(3n+2)(3m+2)(3p+2) = 27nmp + 6(m+n+p) + 8 :zzz:
Jeff Ford said:Not what I got. Try multiplying the first two terms, then multiplying the result by the third term. There is something missing in the middle.
Jeff Ford said:It's not a particularly tidy problem. I got the same answer you did, but wrote it like this
27mnp + 18(mn+mp+np) + 12(m+n+m) + 8
That's about as pretty as it gets.
