Polynomials are algebraic expressions that consist of variables and coefficients. Variables are also sometimes called indeterminates. A polynomial’s degree is the highest or the greatest power of a variable in a polynomial equation. The degree indicates the highest exponential power in the polynomial.
Every polynomial with a specific degree has been assigned a specific name as follows:
|Degree 0||Constant Polynomial|
|Degree 1||Linear Polynomial|
|Degree 2||Quadratic Polynomial|
|Degree 3||Cubic Polynomial|
|Degree 4||Quartic Polynomial|
- A zero polynomial is one where all the coefficients are equal to zero. So, the degree of the zero polynomial is either undefined, or it is set equal to -1.
- A first. degree polynomial, i e. a polynomial having one as the highest power, is known as a linear polynomial.
- A second-degree polynomial, i e. a polynomial with two as its highest power, is known as a quadratic polynomial.
- A third-degree polynomial is simply a polynomial that has three as the greatest exponent of variables. It’s also known as a. cubic polynomial.
