The answer is C because when you have similar radicals, you subtract the whole numbers. In this case 3 square root of 2 minus square root of 2, is doing 3 - 1 = 2.
2 square root of 2
Answer:
The quotient is 
Step-by-step explanation:
We first use the remainder theorem to determine whether
is divisible by
:

the remainder is zero which means
is divisible by
.
Now, we could do polynomial long division to find the quotient, but in this case, it turns out that guessing is easier.

is factored as

which means

which means the quotient is
