Question

look at the trinomal :
100k^4+55k^2-75k

write the polynimal as the product of the gcf of all its terms and a polynomial

Answer 1

100 = 2 * 2 * 5 * 5
55 = 5 * 11
75 = 5 * 5 * 3

they all have one 5 in common so you pull out a 5
they all have 1 "k" in common
so you pull out a "k"

5k(20k^3 + 11k - 15)
