If x=1/2 is a zero of the polynomial f(x)=8x^3+ax^2-4x+2, find the value of a?
\n" ); document.write( "-------
\n" ); document.write( "Using synthetic division::
\n" ); document.write( "1/2)....8.....a.....-4.....2
\n" ); document.write( "........8....a+4...(1/2)a-2..|(1/4)a+1\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "--------
\n" ); document.write( "Solve:: (1/4)a+1 = 0
\n" ); document.write( "a = -4
\n" ); document.write( "------------------
