Question

What is the GCF of the following expression: 24z^7-16z^4

Answer 1

I got 6z^4, but I haven't done a problem like that in a little while. Can anyone back me up or prove me wrong? lol

Answer 2

24 = 2^3 * 3
16 = 2^4
The GCF of 24 and 16 = 2^3 = 8

while the GCF of z^4 and z^7 is z^4
therefore, the GCF of them = 8z^4

Answer 3

Oh right. Added the groups of 2 instead of multiplying. Haha. so 8 is right, not 6.

Answer 4

hehe ;P

Answer 5

thank you man can i throw another one out

Answer 6

identify one of the two solutions for : x^2-15x-54=0
