What value of 'c' would make x^2+2/3x+c a perfect square trinomial ?
\n" ); document.write( "x^2 + (2/3)x + c
\n" ); document.write( "Complete the square:
\n" ); document.write( "x^2 + (2/3)x + [(2/3)/2]^2
\n" ); document.write( "x^2 + (2/3)x + (1/3)^2
\n" ); document.write( "x^2 + (2/3)x + (1/9)
\n" ); document.write( "c= 1/9
\n" ); document.write( "=============
