y³ - y. Classify the following as a constant, linear, quadratic and cubic polynomials
Solution:
Given, the polynomial is y³ - y
We have to classify the polynomial based on the degree.
The highest degree exponent term of the polynomial is known as the degree of the polynomial.
Types of polynomial based on degree,
1) zero polynomial - all the coefficients of the polynomial are zero.
2) Constant polynomial - polynomial with highest degree as zero, it has no variable only constants.
3) Linear polynomial - polynomial with highest degree as one
4) Quadratic polynomial - polynomial with highest degree as two
5) Cubic polynomial - polynomial with highest degree as three.
6) Bi-Quadratic or quartic polynomial - polynomial with highest degree as four.
The highest degree of exponent in y³ - y is 3.
Therefore, y³ - y is a cubic polynomial.
✦ Try This: Classify the following as a constant, linear, quadratic and cubic polynomials : 5a²+3
Given, the polynomial is 5a² + 3
We have to classify the polynomial based on the degree.
The highest degree of exponent in 5a² + 3 is 2.
Therefore, 5a² + 3 is a quadratic polynomial.
