Given polynomial has 3 terms ,
![-2x^2, -x , +2](https://img.qammunity.org/2020/formulas/mathematics/middle-school/m4bohocrbki6422eooz6dtgzv6xrnrwy5n.png)
If a polynomial has 3 terms then it is called as a trinomial
In the given polynomial , there is only one variable x. we can see that the highest exponent is 2.
so the degree of the polynomial is also 2
