Take note that sqrt%289y%2B27%29=sqrt%289%28y%2B3%29%29=sqrt%289%29%2Asqrt%28y%2B3%29=3%2Asqrt%28y%2B3%29. If you treat sqrt%28y%2B3%29 as one whole term, then you can combine the terms 3%2Asqrt%28y%2B3%29 and sqrt%28y%2B3%29 to get %283%2B1%29%2Asqrt%28y%2B3%29=4%2Asqrt%28y%2B3%29


So sqrt%289y%2B27%29%2Bsqrt%28y%2B3%29=4%2Asqrt%28y%2B3%29
