I need guidance on how to solve this first problem and hopefully I'll be able to solve the rest from there.

It says:
Factor out the greatest common factor from each polynomial.

-16x^4-32x^3-80x^2

hartnn · Answer

'greatest common factor' 
lets take it term by term, what do you understand by the term common ?

anonymous · Answer

The term common?

hartnn · Answer

yeah, like common means the term(variable or constant) present in all the terms, right ?

anonymous · Answer

Do you want me to find the greatest common factor?

hartnn · Answer

well, thats what the question asks...

hartnn · Answer

can you find it out on your own ?

anonymous · Answer

I'm not sure. I write out the factors of each coefficient then multiply the ones they have in common, right?

hartnn · Answer

correct, did you try that for this Question ?

anonymous · Answer

Yes and I got a big number so I'm kind of doubting it. I got 1024

hartnn · Answer

that must not be COMMON to all terms. 
you multiply the common terms just once, like in 
64+100 = 4*16 + 4* 25
common term is just 4 and not 4*4

did you get how i break up -16x^4 ? can you break up other 2 terms ?
