3x2(that is x squared)-2x+1+x2(xsquared)+2x-9

so I made it

3xsquared+xsquared=4xsaqured

-2x+2x=0

the answer is: 4xsquared-(-8)=4xsquared+8

Then it asks the type of polynomial?

I thought it was binomial

Are these correct?

Thank you for your help

= 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)
