### CBSE Class 9 Maths Syllabus For Number Systems

**1. Real Numbers (10 Periods)**

1. Review of representation of natural numbers, integers, rational numbers on the number line. Rational numbers as recurring/ terminating decimals. Operations on real numbers. √2 , √3

2. Examples of non-recurring/non-terminating decimals. Existence of non-rational numbers (irrational numbers) such as their representation on the number line.

3. Rationalization (with precise meaning) of real numbers of the type (and their combinations) where x and y are natural numbers and a and b are integers.

Unit 1.4 &1.5 are deleted

6. Recall of laws of exponents with integral powers. Rational exponents with positive real bases (to be done by particular cases, allowing learners to arrive at the general laws.)

### CBSE Class 9 Maths Syllabus For Algebra

**1. Polynomials (15 Periods)**

Definition of a polynomial in one variable, with examples and counter examples. Coefficients of a polynomial, terms of a polynomial and zero polynomial. Degree of a polynomial. Constant, linear, quadratic and cubic polynomials. Monomials, binomials, trinomials. Factors and multiples. Zeros of a polynomial. Factorization of ax^{2} + bx + c, a ≠ 0 where a, b and c are real numbers, and of cubic polynomials using the Factor Theorem.

Recall of algebraic expressions and identities. Verification of identities:

(*x *+ *y *+ *z*)^{2} = *x*^{2} + *y*^{2} + *z*^{2} + 2*xy* + 2*yz* + 2*zx*

(*x *± *y*)^{3} = *x*^{3} ± *y*^{3} ± 3*xy *(*x *± *y*)

*x*^{3 }+ *y*^{3 }+* z*^{3 }– 3*xyz* = (*x *+ *y* + *z*) (*x*^{2} + *y*^{2} + *z*^{2} – *xy* – *yz* – *zx*)

and their use in the factorization of polynomials.

**2. Linear Equations in Two Variables (10 Periods)**

Recall of linear equations in one variable. Introduction to the equation in two variables. Focus on linear equations of the type ax + by + c = 0. Prove that a linear equation in two variables has infinitely many solutions and justify their being written as ordered pairs of real numbers, plotting them and showing that they lie on a line. Graph of linear equations in two variables. Examples, problems from real life, including problems on Ratio and Proportion and with algebraic and graphical solutions being done simultaneously.

### CBSE Class 9 Maths Syllabus For Coordinate Geometry
