Define Polynomial
A polynomial is an expression consisting of one or more terms, each of which is an integer, real number, or complex number, raised to a nonnegative integer power.

About Polynomials
A polynomial is an expression consisting of a sum of one or more terms, each of which is an algebraic equation. The terms are usually numbers, but they can also be variables. The polynomial expression is usually written with the terms descending in order of degree, from the highest power to the lowest power.
For example, the expression 2×3 + 5×2 – 7x is a polynomial. The highest power of x is 3, and the lowest power is 2. The degree of the polynomial is 3.
Polynomials can be added, subtracted, multiplied, and divided. In order to do so, the coefficients of like terms must be aligned. For example, the expression 2×3 + 5×2 – 7x can be rewritten as 2×3 + 5×2 – 7x = (2×3 – 7x) + (5×2 – x).
Further, the real numbers that are used in the polynomials can also be used to express different terms in the grade 9 math polynomial worksheets. Similar to how the certain numbers are polynomials without any variables, they are known as constant polynomials.
In theory, the constant polynomial 0 is also known as zero polynomial. Degree of the polynomial is the highest power that is available to the suggested polynomial. Consider an example where x^{3} + y^{3} + 3xy(x + y), the degree of the polynomial is 3. In a situation where the degree of the sum is a zero, the constant polynomial is a non zero.
Apart from these, polynomials can be further categorised into the suggested three types:

Linear Polynomial – of degree one.

Quadratic Polynomial – of degree two.

Cubic Polynomial – of degree three.

Solved Problems
Q1. Define the suggested degree of each polynomial that is listed below.
(i) 5×3 + 4×2 + 7x
(ii) 4 – y2
(iii) 5t – √7
(iv) 3
Solution:
(i) The given polynomial is 5x^{3} + 4x^{2} + 7x.
The suggested equation provides us with a situation where 3 is the highest power of the variable x. So, the degree of the polynomial is 3.
(ii) The given polynomial is 4 – y^{2}. 2 becomes the highest power of the suggested variable that is, y = 2. So, the degree of the polynomial is 2.
(iii) In the suggested polynomial of the situation where 5t – √7. The highest power of variable t is 1. So, the degree of the polynomial is 1.
(iv) Since, 3 = 3x° ∵x°=1
$\because x\xb0=1$The equation suggests that the degree of the polynomial for the given equation is a 0.

Q2. Verify whether 2 and 0 are zeroes of the polynomial x^{2} – 2x.
Solution :
Let p(x) = x^{2} – 2x
Then p(2) = 22
– 4 = 4 – 4 = 0 and p(0) = 0 – 0 = 0
The solution suggests that the sum 0 and 2 are both the zeroes of the polynomial x^{2} – 2x.
Listed below are the list of observations around the sums:
(i) The resultant sum of a polynomial doesn’t really have to be a 0.
(ii) The term of a zero polynomial might be a 0.
(iii) Polynomials might comprise of more than one zero
