Tamba simplified \(4(3x-1)\). Describe the error.

Tamba's simplification: \(4(3x-1) = 12x - 1\)

You multiply the -1 by 4 as well giving you the answer 12x-4

The error she made is when she did distributive property, she did this:
4(3x) is 12x. That is correct.
Then she did this:
4(-1)= -1
that is the error. 4 times -1 is -4, not one. The actual answer is 12x-4

Tamba incorrectly simplified 4 ( 3 x − 1 ) by stating it equals 12 x − 1 . The correct application of the distributive property gives 12 x − 4 . The mistake was in multiplying 4 with − 1 .
