\n" ); document.write( "
\"5x%5E2+-+9x+%2B+4+=+0\"
\n" );
document.write( "\"5x%5E2+-+9x+=+-+4\" ------ Moving the constant or c to the right side
\n" );
document.write( "\"5x%5E2%2F5+-+%289%2F5%29x+=+-+4%2F5\" ------ Dividing entire equation by 5 to get a leading coefficient of + 1
\n" );
document.write( "\"x%5E2+-+%289%2F5%29x+=+-+4%2F5\"
\n" );
document.write( "\"x%5E2+-+%289%2F5%29x+%2B+%289%2F10%29%5E2+=+-+4%2F5+%2B+%289%2F10%29%5E2\" ------ Taking \"1%2F2\" of b, squaring it, and adding the result to both sides of equation
\n" );
