NCERT Exercise 2.2 Solutions for Class 10 Maths Chapter 2 Polynomials in Hindi Medium and English Medium updated for session 2025-26. Get the revised solutions of ex. 2.2 NCERT Class 10 mathematics based on new syllabus and new textbooks published for academic year 2025-26.
NCERT Exercise 2.2 Solutions for Class 10 Maths
For Class 10 Maths NCERT Exercise 2.2, focus on mastering the algebraic relationships between the zeroes of polynomials and their coefficients. NCERT 10th Math exercise emphasizes finding zeroes of quadratic polynomials and verifying their relationships with coefficients. Begin by revisiting the factorization techniques you learned in earlier classes, especially the method of splitting the middle term. Solve a variety of problems where you calculate zeroes and then confirm their sum and product match the coefficients. This will help you get comfortable with applying these concepts during exams.
Practice solving 10th Math exercise problems without looking at the solution steps to simulate exam conditions. Make sure to work on quadratic polynomials with different forms to cover all possibilities. Reviewing the derivation of relationships between zeroes and coefficients can give you deeper insights, which is helpful for answering conceptual questions that may accompany calculation-based ones in the exam.

Important Questions of 10th Maths Exercise 2.2
What do you understand by value of p(x) at k?
If p(x) is a polynomial in x, and if k is any real number, then the value obtained by replacing x by k in p(x), is called the value of p(x) at x = k, and is denoted by p(k).
What is zero of a polynomial?
A real number k is said to be a zero of a polynomial p(x), if p(k) = 0.
How do we find the zeros of a quadratic polynomial graphically?
The zeroes of a quadratic polynomial ax² + bx + c, a ≠ 0, are precisely the x-coordinates of the points where the parabola representing y = ax² + bx + c intersects the x-axis.
How many zeros are there of a quadratic polynomial?
A polynomial of degree 2 has at most two zeroes.
