Answer:
For
, Leading coefficient is -2, Degree is 2, Constant term is 0
For
, Leading coefficient is -25, Degree is 2, Constant term is 9
For
, Leading coefficient is 1, Degree is 5, Constant term is -1
Step-by-step explanation:
Given:
Polynomials:

To find: leading coefficient, constant term and degree
Solution:
Leading coefficient is the coefficient of the variable with the highest power.
Degree is the highest power of the variable.
The term of degree 0 is the constant term of a polynomial.
For
,
Leading coefficient is -2
Degree is 2
Constant term is 0
For 
Leading coefficient is -25
Degree is 2
Constant term is 9
For 
Leading coefficient is 1
Degree is 5
Constant term is -1
