4X^2 + 2x - 3 = 0
\n" ); document.write( "or 4x^2 + 2. 2 x .1/2 + (1/2)^2 -(1/2)^2 -3 =0
\n" ); document.write( "or (2x + 1/2)^2 - (1/4 +3) =0
\n" ); document.write( "or ( 2x +1/2)^2 = 13/4
\n" ); document.write( "or 2x+1/2 = +- sqrt(13/4)
\n" ); document.write( "or 2x = +-sqrt 13/2 -1/2
\n" ); document.write( "or x = 1/2(+-sqrt 13/2 -1/2)
\n" ); document.write( " = 1/4(+- sqrt 13 -1) \n" ); document.write( "
