You can put this solution on YOUR website!
+3%2Asqrt%282%29+%2B+5%2Asqrt%282%29+
You have to see that the thing to factor out
is +sqrt%282%29+
+sqrt%282%29%2A%28+3+%2B+5+%29+
+8%2Asqrt%282%29+
------------
If it's confusing, just say +x+=+sqrt%282%29+
Then you have:
+3x+%2B+5x+=+8x+
Now put the +sqrt%282%29+ back in
