Astudent expanded an expression, as shown. is the student's work correct? explain why or why not.     −6 ( 4x − 2/ 13 ) −6(4x) + 6 ( − 2/13) −24x − 12/13

The student made an error by expressing the product of two negative signs as a negative sign instead of a positive sign to have a correct expression of  -24x + 12/12

Expressions are functions having more than one term.

Given the expression expanded by a student as   −6 ( 4x − 2/ 13 )

Expanding using the distributive theorem;

= −6 ( 4x − 2/ 13 )

= -6(4x) -6(-2/13)

= -24x + 6(2/13)

= -24x + 12/12

The student made an error by expressing the product of two negative signs as a negative sign instead of a positive sign to have a correct expression of  -24x + 12/12
