$\"4x%5E2-36=0\"$
\n" ); document.write( "add 36 to both sides of the equation
\n" ); document.write( " $\"4x%5E2=+36\"$
\n" ); document.write( " $\"x%5E2=+36%2F4\"$
\n" ); document.write( " $\"+x%5E2+=9+\"$
\n" ); document.write( " $\"+x=sqrt%289%29+\"$
\n" ); document.write( "x= +- 3
\n" ); document.write( "positive root is 3 \n" ); document.write( "

\n" );
