What is the GCF of the terms of the polynomial - 16y4 + 12y2 - 4y?

The GCF is - 4y

Step-by-step explanation:

Given the polynomial expression - 16y4 + 12y2 - 4y?

If we carefully traverse all the terms we can factor out 4y from all the terms

=-4y (4y³-3y+1) which is similar to the original expression

Hence the greatest common factor GCF = - 4y

The Greatest Common Factor (GCF) is the largest number that will divided evenly into that number.
