The second one is correct
Answer:
which agrees with option A in the list of possible answers
Step-by-step explanation:
A vertical compression by a factor 9 is represented by the transformation:

Therefore the answer to the problem is:

C^2 is GCF for Part A
= c^2(3x^2 + 2x - 1)
= c^2(3x - 1)(x + 1)
Part B
x^2 - 2x + 1
= x^2 - x - x + 1
= x(x - 1) - 1(x - 1)
= (x - 1)^2
Part c
x^2 - 64
= (x + 8)(x - 8)
Answer:
35 x 1 = 35
