(6v^3+42v)/(2v^2+26v+84)
Kisachek [45]
Answer:
_______________________________________________
The simplied version is:
_______________________________________________
                " \frac{3v(v^2+7)}{(v^2+13v+42)}  "  ;

or; write as:  " \frac{3v(v^2+7)}{(v+7)(v+6)}  " .
_______________________________________________
Explanation:
_______________________________________________
Given:
_______________________________________________
     " \frac{6v^3 +42 v}{2v^2 +26v + 84}  " ;
_______________________________________________
     →  Factor out a "6v"\frac{6v(v^2+7)}{2(v^2+13v+42)} in the "numerator"; & factor out a "2" in the denominator;  as follows:
____________________________________
→ \frac{6v(v^2+7)}{2(v^2+13v+42)} ;
____________________________________
→  " \frac{3v(v^2+7)}{(v^2+13v+42)} " ;
______________________________________________

or; factor out the "denominator" :
______________________________________________
→ (v² + 13v + 42) =  (v+7)(v+6) ;
______________________________________________
and write as: 
______________________________________________
→  " \frac{3v(v^2+7)}{(v+7)(v+6)} " .
______________________________________________
