$\"sqrt%284z%2B12%29=+sqrt%289z-11%29\"$
\n" ); document.write( "Square both sides.
\n" ); document.write( " $\"4z%2B12=9z-11\"$
\n" ); document.write( " $\"-5z=-23\"$
\n" ); document.write( " $\"z=23%2F5\"$
\n" ); document.write( "Verify the solution.
\n" ); document.write( " $\"sqrt%284z%2B12%29=+sqrt%289z-11%29\"$
\n" ); document.write( " $\"sqrt%284%2823%2F5%29%2B12%29=+sqrt%289%2823%2F5%29-11%29\"$
\n" ); document.write( " $\"sqrt%2892%2F5%2B60%2F5%29=+sqrt%28207%2F5-55%2F5%29\"$
\n" ); document.write( " $\"sqrt%28%2892%2B60%29%2F5%29=+sqrt%28%28207-55%29%2F5%29\"$
\n" ); document.write( " $\"sqrt%28152%2F5%29=+sqrt%28152%2F5%29\"$
\n" ); document.write( "Leads to a true statement, hence it's a good solution. \r
