Can someone help me figure this out: Factor 12y^2-27? I keep getting the steps confused.

8 0

Factor out the gcf first.

3(4y^2-9)

The binomial inside is a perfect square so keep factoring.

3(2y+3)(2y-3)

The pair of binomials cannot be further factored so stop there.

What is the GCF of 44 and 110?

In order to find the GCF of these two numbers we need to list all their factors and find the first common one so.

44: 1,2,4,11,22,44
110, 1,2,5,10,11,22,55,110

Since 22 is the highest number that both share and its common, that would be your answer. Answer: 22.
