Add:
sqrt%289y%2B27%29%2Bsqrt%28y%2B3%29 Rewrite the first term as:
sqrt%283%5E2%2Ay%2B3%5E2%2A3%29 Take the square root the 3%5E2
3%2Asqrt%28y%2B3%29 so nopw you have:
3%2Asqrt%28y%2B3%29%2Bsqrt%28y%2B3%29+=+highlight%284%2Asqrt%28y%2B3%29%29

Just by seeing the (y+3) you should wonder if it is a factor of 9y+27

+sqrt%289y%2B27%29+++sqrt%28y%2B3%29+
