Question

Simplify the rational expression.

\[\frac{ 3n^3-36n^2+105n }{ 49n-7 }\]

Answer 1

First find the common factors. In the numerator you have one numerical and a variable and in the denominator you have a integer factor.

Answer 2

Is it \[\frac{ 3(n^3-12n^2+35 }{7(7n-1) }\] ? @daniel.ohearn1
