What is the greatest common factor of 4xy^2 and 20x^2y^4

greatest common factor is 4xy^2

Step-by-step explanation:

the greatest common factor of 4xy^2 and 20x^2y^4

BReak the factors for each term

4xy^2         ---> 2*2*x*y*y

20x^2y^4 > 2*2*5*x*x*y*y*y*y

Now we look at the common factors for both terms

2*2*x*y*y. Multiply it to get GCF

So greatest common factor is 4xy^2

answer is the third choice:

3x^5+4x^4+x^3+2x^2-10x-7=0
