Question 283115
Hello, 
Let's first remove the fractions by multiplying by 6z. This will give us:
6z^2-24+12z=z Now subtract z from both sides to get:
6z^2+11z-24=0 Now use the quadratic Form to solve:
{{{z = (-b +- sqrt( b^2-4*a*c ))/(2*a) }}} Plug in the values:
z = (-11 +- sqrt( 121+576))/(12) Simplify to:
z=-11+-sqrt697/12 
There you go.
