Question 401495
{{{(z^2-2z-24)/(8z^3-7z)}}}* {{{(64z^3-49z)/(6z-36)}}}
...
{{{((z-6)(z+4))/(z(8z^2-7))}}}* {{{z(64z^2-49)/(6(z-6))}}}
...

{{{((cross(z-6))(z+4))/((cross(z))(8z^2-7))}}}* {{{(cross(z))(64z^2-49)/(6(cross(z-6)))}}}

..

{{{(z+4)/(8z^2-7)}}}X{{{((8z+7)(8z-7))/6}}}

{{{((z+4)(8z+7)(8z-7))/6(8z^2-7)}}}
