<span>5ab^2 + 10ab
5ab^2 = 5ab *(b)
10ab = 5ab *(2)
so GCF of </span>5ab^2 + 10ab = 5ab
Easy ill tell u and then do a equation first sense it has - it means u have to subtract alright it goes like this. 17,1
9,3
--------
7,8
and this is ur answer as u see in my equation ur welcome only give me brainiest only if im right
Well what i think you're asking here...I apologie if I'm wrong but what I did was
f(-1) = 4 * 7^t = 4/7
and
f(2) = 4 * 7^t = 196.
Is this what you wanted if not I can...try another way.
