Find the LCM.
-$$\mathrm { n } , 9 + \mathrm { n } , 9 - \mathrm { n }$$
A) $n ^ { 2 } + 81$
B) $n + 9$
C) $\mathrm { n } ( 9 + \mathrm { n } ) ( 9 - \mathrm { n } )$
D) $81 \mathrm { n } ^ { 2 }$

Question

Quizplus · Accepted Answer

The LCM of $n$, $9 + n$, and $9 - n$ can be found by multiplying them together since they are relatively prime (no common factors other than 1). This gives $n(9 + n)(9 - n)$, which simplifies to $n(n^2 - 81)$, but the correct representation as per the options given is $n(9 + n)(9 - n)$.
