# Algebra Formulas for Class 9 : Algebraic Expressions

Algebra Formulas for Class 9: Algebra is a branch of mathematics in which universal symbols and letters are used to represent quantities and numbers in equations and formulas. Algebra is divided into two sections: Elementary Algebra and Modern Algebra (Abstract Algebra). Algebraic expressions formulas for Class 9 have been included in the CBSE curriculum so that students may comprehend the value of Algebra in their daily lives.

In CBSE Class 9, the chapter on algebraic expressions and identities is introduced. Algebra is one of the most straightforward and high-scoring topics. However, if you don’t recall different Maths formulas for Class 9 Algebra and how to use them in Algebraic Expressions and identities, it can get a bit tough. To make it easier for students, we have included algebraic equations examples with answers on this page. Continue to read on to find out.

### Maths Algebraic Identities for Class 9

Do you know the difference between an algebraic formula (identity) and an algebraic expression? An algebraic formula is an equation that is a rule written using mathematical and algebraic symbols. It always involves algebraic expressions on both sides. Moreover, equality will hold true for any values of variables.

On the other hand, an algebraic expression is not separated by an equal sign. An algebraic expression contains two things – Variables and Constants. The value of the variable changes in different expressions while the constant remains the same. We can understand the difference between the two from the following example:

(a + b)2 =a2 + 2ab + b2 is an algebraic formula and here,

(a + b)2 is an algebraic expression.
a2+ 2ab + b2 is an algebraic expression.

The LHS and RHS of an algebraic formula are always equal for any value of the variables in it. This property allows us to deduce the result on RHS if we know the values to the left of an expression.
