Question

Marcel made an error when he used the distributive property to write an equivalent

Answer 1

Answer: Upper left corner

Explanation:

The error happens in step 2. Notice that x is not part of the second term 16, so there's no way to factor x from it unless you want a fraction to result.

The second step should be 8(4x-2)

Another way to factor is to say 16(2x-1)
