Answer: True
Step-by-step explanation:
We know that the quadratics polynomials have this form:

You need to remember that the degree of a polynomial is given by its highest exponent.
You can observe in the quadratic polynomial
that the highest exponent is "2", which is the exponent of the term 
Therefore, since the highest exponent is "2", you should conclude that the degree of the polynomial is 2.
Then, you can say that a quadradic polynomial has degree 2.
