Question

simplify by removing factors of 1.
7m^2+7m/63 m^2+49m

Answer 1

\[\Large \frac{7m^2+7m}{63m^2+49m}\]


\[\Large \frac{7m(m+1)}{63m^2+49m}\]


\[\Large \frac{7m(m+1)}{7m(9m+7)}\]


\[\Large \frac{\cancel{7m}(m+1)}{\cancel{7m}(9m+7)}\]


\[\Large \frac{m+1}{9m+7}\]
So \[\Large \frac{7m^2+7m}{63m^2+49m}=\frac{m+1}{9m+7}\]
