Updated on July 18, 2023

Answer: A third degree polynomial, also known as a cubic polynomial, has the general form ax^3 + bx^2 + cx + d, where a, b, c, and d are coefficients and a ≠ 0.

## Understanding Polynomials

A polynomial of degree 3, or a cubic polynomial, has the general form ax^3 + bx^2 + cx + d, where a, b, c, and d are real numbers and a is not zero. The degree of a polynomial is the highest power of x in its expression. A cubic polynomial has one to three roots or zeros.

## FAQ on Polynomials

### What is a polynomial?

A polynomial is an expression consisting of variables and coefficients, involving operations of addition, subtraction, multiplication, and non-negative integer exponentiation of variables.

### What is a second degree polynomial?

A second degree polynomial, also known as a quadratic polynomial, has the general form ax^2 + bx + c, where a, b, and c are coefficients and a ≠ 0.

### What is a zero or root of a polynomial?

A zero or root of a polynomial is a value of x that makes the polynomial equal to zero.
