A student's work to simplify and combine radicals is shown below. Select the statement which best applies to the sample mathematical work.
Given \[-\sqrt{12}-2\sqrt{3}\], I observe that \[\sqrt{12}=\sqrt{4*3}\] and that 4 is a perfect square, so I simplify to the expression \[-2\sqrt{3}-2\sqrt{3}\]. I can then combine these terms to get \[-4\sqrt{3}\], which is my answer.
OpenStudy (imsleeziboii):
A.The student erroneously attempted to combine terms with different indices
B.The student did not properly simplify the radicals
C.The student did not properly combine the radical terms.
D.
The work shown above is correct and there is no error.

what?
OpenStudy (soprano.h.d0816):
The way the student in the problem worked out the problem, it's wrong. The answer, I believe is correct, but the work isn't. The student attempted to combine the terms using different methods.
OpenStudy (imsleeziboii):
so what letter would that be?
OpenStudy (soprano.h.d0816):
Which letter has kind of the same thing I said in my previous comment?
OpenStudy (imsleeziboii):
None of them looked like it
