Question

(n^4)/(n^2+2n+1) (7)/(n^2-8n-9) need help finding the least common denominator

Answer 1

this would look only half as hard if written as follows:\[(n^4)/(n^2+2n+1) .and. (7)/(n^2-8n-9)\]

Answer 2

or, better yet,
\[\frac{ n^4 }{ n^2+2n+1 }, \frac{ 7 }{ n^2-8n-9 }\]

Answer 3

suggestion: factor both denominators. Then, think about what "LCD" means in this context. How would you find the LCD?
