Given:
The expression is
[tex]9\sqrt{x}-3\sqrt{x}[/tex]
To find:
The result after subtracting the radicals.
Solution:
We have,
[tex]9\sqrt{x}-3\sqrt{x}[/tex]
We need to combine these terms.
Taking out common factors, we get
[tex]=(9-3)\sqrt{x}[/tex]
[tex]=6\sqrt{x}[/tex]
The result after subtracting the radicals is [tex]6\sqrt{x}[/tex].
Therefore, the correct option is B.
