Adding and subtracting polynomials?!

[Teenagelobotomy]

Could someone help/explain to me this equation?

(2x^2+7x+1)+(x2-2x+8)

 

[tkhunny]

I can help you see that it isn't an equation and since you didn't give us a problem statement, no one knows what to do with the expression you have provided.

So which format are you using, and how far have you gotten? Where are you stuck?

Please reply with specifics. Thank you.

I have gotten absolutely nowhere.

Im supposed to find the sum of:
(2x^2+7x+1)+(x^2-2x+8)

I have gotten absolutely nowhere.
