A student expanded an expression, as shown. Is the student's work correct? Explain why or why not.
No, the work is not correct. The distributive property was not used properly to expand the expression. Negative 6 should be multiplied by both terms in the parentheses. The second product should be -6 times -2/13 to get positive 12/13.
That was the sample response.
