Topics Covered in Exercise 2.2 Class 10 Mathematics Questions
It is advised that students thoroughly understand the topics covered by the ex 2.2. NCERT solutions for class 10 maths chapter 2 Polynomials ex 2.2 topics are mentioned below.
1. 
Relationship between Zeroes and Coefficients of a Polynomial 

Relationship between Zeroes and Coefficients of a Polynomial  A polynomial is an expression with lots of different terms. Depending on the degree of polynomial, it can be divided into different types, like a linear polynomial (x), a quadratic polynomial (x2), or a cubic polynomial (x3). Based on the degree, we can easily find the zeros of any polynomial. A polynomial is a function whose coefficients are the constant values multiplied by its variables.
Here, you will learn the relationship between Zeroes and Coefficients of a Polynomial.
Linear Polynomial  Linear polynomials are generally defined as y = ax + b
We know that in the case of zeros, we have to find the point where y = 0. The general equation for y = 0 is:
y = ax + b
⇒0 = ax + b
x = b/a
This tells us the relation between zero and the coefficient of the linear polynomial.
for a linear equation (y = ax + b, a ≠ 0), the graph of ax + b is a straight line that cuts the xaxis at (b/a, 0)
Quadratic Polynomial  A Quadratic Polynomial is a degree of 2 polynomials. The zeroes of this polynomial can be determined using a variety of methods, including

Factorization Method

Using Quadratic Formula.
Since Quadratic Polynomial has highest degree 2, There are two zeroes of the Quadratic Polynomial.
The relation between the zeroes of a quadratic polynomial and its coefficient is:
For any polynomial P(x) = ax2 + bx + c if the zeroes of the quadratic polynomial are α, and β then,

Sum of the zeroes (α + β) = – Coefficient of x / Coefficient of x2 = b/a

Product of the zeroes (αβ) = Constant term / Coefficient of x2 = c/a
Cubic Polynomial  A cubic polynomial is a degree 3 polynomial, and because it has its highest degree of 3, there are three zeroes in a cubic.
Let’s suppose the zeros of the polynomials ax3 + bx2 + cx + d = 0 are p, q, and r, The relationship between these zeros and the polynomial and its coefficient will be given as follows:
Given Cubic Polynomials: ax3 + bx2 + cx + d = 0
If α, β, γ are the zeroes of the cubic polynomial ax3 + bx2 + cx + d, then

The sum of zeros, α + β + γ is b/a = – Coefficient of x2/ coefficient of x3

The sum of the product of zeros, αβ+ βγ + αγ is c/a = Coefficient of x/Coefficient of x3

The product of zeros, αβγ is d/a = – Constant term/Coefficient of x3
Tips for Solving Exercise 2.2 Class 10 Chapter 2 Polynomials
You can gain a thorough comprehension of the terms and concepts used in the questions of Ex 2.2 by following the tips given here.

Exercise 2.2 of NCERT solutions class 10 maths chapter 2 Polynomials may be solved by dividing the quadratic polynomial into multiple factors and writing each term separately. After separating the terms, you can take out the common factor and obtain the result. In this case, the remaining two terms can be considered to be factors.

Once students are familiar with polynomial degrees, how tosplit middle terms, and the relationship between the terms, they can easily solve the questions of ex 2.2 .
