Answer:
the polynomial
is trinomial
the degree of the polynomial is 2
Step-by-step explanation:
![-2x^2-x+2](https://tex.z-dn.net/?f=-2x%5E2-x%2B2)
Given polynomial has 3 terms , ![-2x^2, -x , +2](https://tex.z-dn.net/?f=-2x%5E2%2C%20-x%20%2C%20%2B2)
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
