x^2-2/3x=0
\n" ); document.write( "take half of b, square it, and add to both sides (2/6)^2 = (1/3)^2 = 1/9:
\n" ); document.write( "x^2-2/3x+1/9 = 1/9
\n" ); document.write( "(x-1/3)^2 = 1/9
\n" ); document.write( "x-1/3 = sqrt(1/9)
\n" ); document.write( "x = sqrt(1/9) + 1/3
\n" ); document.write( "x = +-1/3 + 1/3
\n" ); document.write( "x = {0, 2/3}\r
