Solution

(i) If the polynomial is with degree 1 it is a Linear Polynomial.
If the polynomial is with degree 2 it is a Quadratic polynomial
If the polynomial is with degree 3 it is a Cubic polynomial.

a) The degree of the polynomial $5 x^{4} + 5 x^{3} + 9 x + 6$ is 4. Hence, it is a biquadratic.
b) The degree of the polynomial $2 x^{2} + 9 x + 6$ is 2. hence, it is a Quadratic polynomial.
