Show all arithmetic work on how i got the answer

2 Question 2. (4 pts) Consider the following polynomial that can be factored by Factoring by Grouping. Please complete the following questions, show all your arithmetic work as shown in class or in lecture video, and write your answers below. The use of Al is not allowed. Al generated answers will count as partial credit. 16 x3- 4x- 4x+1 #1. Group the first two terms by underlining the first two terms. #2. Group the last two terms by underlining the last two terms. #3. Factor out the GCF between the first two terms and last two terms. Hint: The answer should look similar to the following. ?x (2x- 2)-2(2x- 2) #4. From the correct answer of #3, there are only two terms and what's inside of parentheses should match. So, factoring the GCF again
