Question

what is algebraic expressions?
explains me full.

Answer 1

an expression obtained by a finite number of the fundamental operations of algebra upon symbols representing numbers

Answer 2

Step-by-step explanation:

Algebraic expression is the expression having constants and variable. It can have multiple variable and multiple power of the variable.

Example

10x , 2x -3 etc

An equation is a statement of an equality containing one or more variables..

A variable takes on different numerical values; its value is not fixed. Variables are denoted usually by letters of the alphabets,

An algebraic equation is an equality involving variables. It says that the value of the expression on one side of the equality sign is equal to the value of the expression on the other side.

Example

5x=25

2x-3=9

Important points to remember

These all above equation contains the equality sign.

The above equation can have more than one variable.

The above equation can have highest power of variable > 1.

The expression on the left of the equality sign is the Left Hand Side (LHS). The expression on the right of the equality sign is the Right Hand Side (RHS).

In an equation the values of the expressions on the LHS and RHS are equal. This happens to be true only for certain values of the variable. These values are the solutions of the equation.

We assume that the two sides of the equation are balanced. We perform the same mathematical operations on both sides of the equation, so that the balance is not disturbed. We get the solution after generally performing few steps
