Answer: Quadratic polynomial
A polynomial is an algebraic expression in which the exponent on any variable is a whole number. 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.
Types of polynomials based on degree
Various types of polynomials based on degree are,
- Linear Polynomial – A polynomial whose degree is one is called a linear polynomial.
- Quadratic Polynomial – A polynomial of degree two is called a quadratic polynomial.
- Cubic Polynomial – A polynomial of degree three is called cubic polynomial.
Given equation y + y2 + 4
The highest power of y + y2 + 4 is 2
The degree of the given eqaution is 2
∴ y + y2+ 4 is a quadratic polynomial.
