Factor the expression using the GCF 100-80

The prime factorization of 100 is: 2 x 2 x 5 x 5.

The prime factorization of 80 is: 2 x 2 x 2 x 2 x 5.

The prime factors and multiplicities 100 and 80 have in common are: 2 x 2 x 5.

2 x 2 x 5 is the gcf of 100 and 80.

gcf(100,80) = 20.

Step-by-step explanation:

PLEASE MARK ME BRAINLIEST

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation
