do you know the rule for manipulating radicals
so use this and taking out the common factor of
then use the fact that
THe link below shows a picture of a problem i need help in how can i solve it? what are the step by step? you can also help me solve it so i can find ot how to solve my other problems. Thanks ;]

We start with:
We can simplify the second radical by pulling out a factor of 9:
Then the square root of 9 becomes 3:
We combine the like terms:
We can also take out a factor of x^2:
The square root of x^2 is the absolute value of x:
And the problem is done, because cannot be further broken down.
