\n" );
document.write( "The Idea is to Let n =    
\n" );
document.write( "  2n^2 - 5n - 3 = 0
\n" );
document.write( "(2n+1)(n-3)= 0
\n" );
document.write( "  (2n+1)= 0, n = -1/2,  
\n" );
document.write( "0r (n-3)= 0, n = 3 ,    x = 1/27 
\n" );
document.write( "n =  , n^3 = 1/x (Cubing both sides)    0r x = 1/n^3
\n" );
document.write( " \n" );
