The question is simply and answer in standard form
3x2(that is x squared)-2x+1+x2(xsquared)+2x-9

3xsquared+xsquared=4xsaqured
-2x+2x=0

Then it asks the type of polynomial?
I thought it was binomial

Are these correct?

• Math -

3x^2 - 2x + 1 + x^2 + 2x - 9

= 4x^2 - 8

don't understand how you got +8
( +1-9 = -8)

yes, it is a binomial , (there are two terms, "bi" means 2)
