Question 205388
if the problem is like this:
{{{((16x^2 - 9)/(16x^2 - 24x +9))/(8x+6)}}}

then the solution should be:
{{{((16x^2 - 9)/(16x^2 - 24x +9))/(8x+6)}}}
{{{((4x-3)(4x+3)/(4x-3)(4x-3))*(1/(8x+6))}}}
{{{(((cross(4x-3))*(4x+3))/((cross(4x-3))*(4x-3)))*(1/(2(4x+3)))}}}
{{{((cross(4x+3))/(4x-3))*(1/(2*(cross(4x+3))))}}}
{{{1/(2(4x-3))}}}
