Question 1023476
 I need help simplifying this equation

y= (x-8)/((cuberootx) -2)
--------
{{{y = (x-8)/(root(3,x) - 2)}}}
The object is to rationalize the DEN.
Use the fact that {{{a^3 - b^3 = (a-b)*(a^2 + ab + b^2)}}}

-->  {{{y = (x-8)*((root(3,x))^2 + 2root(3,x) + 4)/((root(3,x) - 2)*((root(3,x))^2 + 2root(3,x) + 4))}}}
 {{{y = (x-8)*((root(3,x))^2 + 2root(3,x) + 4)/(x-8)}}}
 {{{y = root(3,x^2) + 2root(3,x) + 4}}}
==================
Equations are usually solved, or the zeroes are found.
