A. p(x)=ax^3+bx^2+cx+d

B. For example: (x+2)+(2x^2+4x+9)=2x^2+5x+11 is a polynomial

Step-by-step explanation:

Degree is the highest power of the exponent in the polynomial.

A third degree polynomial is of form p(x)=ax^3+bx^2+cx+d . Its degree is 3.

This polynomial is in standard form as the terms are ordered from the biggest (3) to the lowest exponent (0).

A polynomial is an expression consisting of variables and coefficients combined together using arithmetic operations. Exponents of variables are non-negative integers.

Polynomials are closed under addition as sum of two polynomial is also a polynomial.

For example: take two polynomials as x+2,2x^2+4x+9

Here,

$(x+2)+(2x^2+4x+9)=x+2+2x^2+4x+9\\=2x^2+5x+11$

2x^2+5x+11 is also a polynomial.
