Grace, Chelsea, and Roan are simplifying the same polynomial expression. Which student's work is correct and why?
Grace
312 - x) - 2(6x - 8)
= 6-3x - 12x + 16
= -3x - 12x + 16 + 6
= -15x + 22
Chelsea
3(2-x) - 2(6x - 8)
= 6-3x - 12x - 16
= -3x - 12x - 16 + 6
= -15x - 10
Roan
3(2 - x) - 2(6x - 8)
= 6 - 3x + 12x - 16
= -3x + 12x - 16 + 6
= 9x - 10
