We can solve the following
\n" ); document.write( " $\"x%5E2%2B3x-5=0+\"$
\n" ); document.write( "by completing th square as\r
\n" ); document.write( "\n" ); document.write( " $\"%28x%2B1.5%29%5E2+-7.25=0\"$
\n" ); document.write( "and solving for x we get
\n" ); document.write( " $\"%28x%2B1.5%29%5E2+=+7.25\"$
\n" ); document.write( " $\"x%2B1.5+=+%2B-sqrt%287.25%29\"$
\n" ); document.write( " $\"x+=+-1.5+%2B-+sqrt%287.25%29\"$
\n" ); document.write( "x ~ 1.193
\n" ); document.write( "x ~ -4.193 \n" ); document.write( "

\n" );
