Answer:
The GCF is - 4y
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.
