You can put this solution on YOUR website!
+3%2Asqrt%282x%5E2%29+%2B+6%2Asqrt%289%29+%2B+8%2Asqrt%282x%5E2%29+%2B+1%2Asqrt%289%29+
When you have a perfect square inside a square root you can extract it easily
Resulting in:
+3x%2Asqrt%282%29+%2B+6%2A3+%2B+8x%2Asqrt%282%29+%2B+1%2A3+
+3x%2Asqrt%282%29+%2B+18+%2B+8x%2Asqrt%282%29+%2B+3+
Add like terms
+11x%2Asqrt%282%29+%2B+21+
