Determine the degree of each term, the degree of the expression, and the type of polynomial (linear, quadratic, cubic, etc)

we have the expression
[tex]-4x^3+6x^2-9x+8[/tex]step 1
Degree of each term
-4x^3 --------> degree 3
6x^2 ------> degree 2
-9x -----> degree 1
8 -----> is a constant (degree 0)
step 2
the degree of the expression is degree 3
step 3
type of polynomial
is a cubic polynomial
