Factor the GCF
12y³-27y

• 3y(4y²-9)
• 9y(3y²-18)
• 4y(3y²-7)
• 9(3y³-9y)

Is this correct:
Factor:  7x²-14x
7(x²-2x)

• yes, it is perfect
• no, you can't divide by 7
• no, you can also take out an x
• no, you should divide by 14

Are you starting to understand the GCF?

• no, i am still totally lost
• sort of, but still kinda confused
• getting there, still need some practice
• yeah! i totally got this!
