An expression is shown below:

3x^3y + 12xy - 9x^2y - 36y

Part A: Rewrite the expression so that the GCF is factored completely. Show the steps of your work.

Part B: Rewrite the expression completely factored. Show the steps of your work. (4 points)

Part C: If the two middle terms were switched so that the expression became 3x^3y - 9x^2y + 12xy - 36y, would the factored expression no longer be equivalent to your answer in part B? Explain your reasoning.

first deal with the numbers 
what is the GCF of  3 ,9 12 and 36?

welshfella · Answer

GCF being the greatets number which divides exactly into all 4 numbers

anonymous · Answer

ok thank you... what about parts B and C??

welshfella · Answer

well to find the GCF we need to deal with the letters as well as the numbers
- which letter is common to all 3 terms/

welshfella · Answer

x or y?
