Astudent's work to simplify & combine radicals is shown below. select the statement which best applies to the sample mathematical work.
given -√12 -2√3, i observe that √12 = √4x3 and that 4 is a perfect square, so i simplify to the expression -2√3 -2√3. i can then combine these terms to get -4√3 which is my answer.
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.
