Question 913046
Factor as much as possible. Afterward, cancel out common terms between the numerator and denominator.


{{{(y^2+16y+63)/(y^2+17y+72)}}}


{{{((y+7)(y+9))/(y^2+17y+72)}}}


{{{((y+7)(y+9))/((y+8)(y+9))}}}


{{{((y+7)*highlight((y+9)))/((y+8)*highlight((y+9)))}}}


{{{((y+7)*cross((y+9)))/((y+8)*cross((y+9)))}}}


{{{(y+7)/(y+8)}}}


---------------------------------------------------------------------------


So {{{(y^2+16y+63)/(y^2+17y+72)}}} simplifies to {{{(y+7)/(y+8)}}}
