Answer:
- (3y)(2x^2 -1x -8xy +4y)
- (3y)(x -4y)(2x -1)
Step-by-step explanation:
<u>Part A</u>: All of the coefficients have a common factor of 3. All of the variable products have a common factor of y, so the greatest common factor of all terms is 3y. The expression can be written as ...
   (3y)(2x^2 -1x -8xy +4y)
__
<u>Part B</u>: The remaining factor can be factored pairwise:
   3y(x(2x -1) -4y(2x -1)) = 3y(x -4y)(2x -1)
