You can put this solution on YOUR website!
You cannot add the square roots of different expressions/values/variables. Treat $\"sqrt%28something%29\"$ as a variable. You cannot add the variables x and y. You can add x and x: x+x=2x. You can only add square roots (or any roots) if what is inside them is the same.
