anonymous · Answer

should i put +x^0 at the end or something?

skullpatrol · Answer

Look at the question again please, in particular look at the value of the exponent :)

anonymous · Answer

yeah the +2x at the end?

that would be +2x^1 , but would i have to write it like that? or couldn't I just leave it as is?

skullpatrol · Answer

What is the value of the highest exponent?

anonymous · Answer

4th power, right? so i add in descending order to 1 power... i'm not really sure
