The NCERT Solutions Class 9 Maths Chapter 2 Linear Polynomials cover every question from the new Ganita Manjari book. This chapter teaches you to read the degree of a polynomial, find its value, and turn word problems into simple linear equations that you can solve step by step.

  • Exercises solved: Exercise Sets 2.1 to 2.6 and all 7 End-of-Chapter problems
  • Main skills: finding degree and coefficients, evaluating polynomials, and forming linear equations
  • Why it matters: it builds the base for algebra and linear equations in Class 10

These solutions are prepared by subject teachers, matched to the current 2026-27 NCERT, and checked step by step so a Class 9 student can follow each line.

What Does Class 9 Maths Chapter 2 Linear Polynomials Cover?

The chapter begins with the idea of a polynomial. You learn what a term, a coefficient, and a degree mean. A polynomial of degree one, like 5x - 3, is called a linear polynomial. You then find the value of a polynomial by putting a number in place of the variable. The NCERT Solutions Class 9 Maths Chapter 2 Linear Polynomials also show how everyday situations, such as savings or age problems, become linear equations that you can solve for one unknown.

Common Mistakes Students Make in Linear Polynomials

Most errors in this chapter come from small slips, not hard ideas. Fix these early and your marks stay safe.

Watch Out: Students often miss a sign while putting a negative number in a polynomial. One wrong sign changes the whole value and loses the full mark.
  • Confusing the degree with the number of terms in a polynomial.
  • Forgetting that a missing term has coefficient 0.
  • Setting up the equation wrongly when the words say "three times" or "after 5 years".

Sample Solved Question from Class 9 Maths Chapter 2

Here is one Exercise 2.2 type word problem, solved step by step, so you can see the method.

Question: The present age of Salil's mother is three times Salil's present age. After 5 years, their ages will add up to 70 years. Find their present ages.

Step 1. Let Salil's present age be x years. Then his mother's age is 3x years.

Step 2. After 5 years, Salil is x + 5 and his mother is 3x + 5.

Step 3. Their ages add up to 70, so (x + 5) + (3x + 5) = 70.

Step 4. Simplify to get 4x + 10 = 70, so 4x = 60 and x = 15.

Final answer. Salil is 15 years old and his mother is 45 years old.

Quick Tip: Always name the unknown first with a letter. A clear "let x be..." line makes the rest of the sum easy.
