Question

All of the following expressions are equivalent to 12w + 6, except:

-1(12w - 6)
(3 + 6w)2
6(1 + 2w)
-1(-12w - 6)

Answer 1

-1 (12w-6)

Explanation:

the original equation does have the 12 negative.

Answer 2

-1(12w - 6) is not equivalent because when the -1 is distributed, the equation becomes -12w + 6, not 12w + 6
