x^2 +7x -2 = 0
\n" ); document.write( "x^2 +7x = 2
\n" ); document.write( "now divide the x coefficient by 2, 7/2 and (7/2)^2 = 49/4
\n" ); document.write( "add 49/4 to both sides of the =
\n" ); document.write( "x^2 +7x +49/4 = 2 +49/4
\n" ); document.write( "factor above equation
\n" ); document.write( "(x-49/4)^2 = 57/4
\n" ); document.write( "take the square root of both sides of =
\n" ); document.write( "x -7/2 = (square root(57))/2
\n" ); document.write( "x = square root(57))/2 +7/2
\n" ); document.write( "x = (square root(57) +7) /2
\n" ); document.write( "now
\n" ); document.write( "x = (7 + square root(57) / 2 and
\n" ); document.write( "x = (7 - square root(57) / 2
\n" ); document.write( " \n" ); document.write( "
\n" );
