Question

1. What is the greatest common factor of 20x^6y+40x^4y^2−10x^5y^5 ?

A. 5x^2y^5

B. 10x^4y

C. 5x^4y

D. 20x^6y

Answer 1

Here, your expression is: 20x^6y+40x^4y^2−10x^5y^5
Now, your coefficients are: 20, 40, 10
So, GCF of 20, 40 & 10 is 10

& Greatest common variable of x^6y, x^4y & x^5y^5 is x^4y
So, Your GCF for whole expression is 10x^4y

In short, Your Answer would be Option B

Hope this helps!
