You can put this solution on YOUR website!
3+√(z-11) = √(z+4)
\n" ); document.write( "-------------
\n" ); document.write( " $\"3+%2B+sqrt%28z-11%29+=+sqrt%28z%2B4%29\"$
\n" ); document.write( "Square both sides
\n" ); document.write( " $\"9+%2B+6sqrt%28z-11%29+%2B+%28z-11%29+=+z%2B4\"$
\n" ); document.write( " $\"6sqrt%28z-11%29+=+6\"$
\n" ); document.write( "Square again
\n" ); document.write( "36(z-11) = 36
\n" ); document.write( "x-11 = 1
\n" ); document.write( "z = 12
\n" ); document.write( " \n" ); document.write( "
