Question 360416
{{{((2z-1)/(z^2+z-6)) - ((3z-5)/(z^2-2z-15)) + ((2z-3)/(z^2-7z+10))}}}
..
{{{((2z-1)/(z+3)(z-2)) - ((3z-5)/(z-5)(z+3)) +((2z-3)/(z-5)(z-2))}}}
LCM = (z-5)(z-2)(z+3)
...
{{{((2z-1)(z-5)-(3z-5)(z-2)+(2z-3)(z+3))/(z-5)(z-2)(z+3))}}}
{{{((2z^2-11z+5)-(3z^2-11z+10)+(2z^2+3z-9))/(z-5)(z-2)(z+3))}}}
{{{((2z^2-11z+5-3z^2+11z-10+2z^2+3z-9))/(z-5)(z-2)(z+3))}}}
{{{((z^2+3z-14))/(z-5)(z-2)(z+3))}}}
