Answer:
Step-by-step explanation:
When we use the distributive property for expanding polynomial products, we often use it in the form ...
(a +b)c = ac +bc
Here, we have ...
(a +b) = (x -1) ⇒ a=x, b=-1
c = (4x+2)
So, the proper application of the distributive property looks like ...
(a +b)c = ac +bc
(x -1)(4x +2) = x(4x+2) -1(4x+2) . . . . . different from the work shown
We must conclude ...
The distributive property was not applied correctly in the first step.
