## Simplifying Expressions

Simplifying Expressions is quite easy when it comes to solving algebraic equations. The technique of simplifying expressions in the most efficient and compact form without altering the value of the original expression is known as simplification of an algebraic expression. If you like to solve algebraic equations then be the first to learn about the tricks in simplifying algebraic expressions with examples given right here. An algebraic expression is a mathematical phrase with variables and constants that are combined using +, -, × & ÷ operational symbols.

How do you Simplify Expressions? Let's scroll down to know more about simplifying algebraic expressions with examples.

## What to remember while simplifying Algebraic Expressions?

Here are the terms used when simplifying algebraic expressions.

A variable is a letter whose value is unknown in an algebraic expression

Coefficient the numerical value used together with a variable

A constant is a term that has a definite value

Then the next factor is Like terms. The Like terms are variables with the same letter and power, sometimes like terms will contain different coefficients

## How do you Simplify Expressions?

Let's check how to Simplify Expressions in an easy way. You can also check out simplifying algebraic expressions examples along with the answer in the below section.

First, remove any grouping symbol like brackets and parentheses by multiplying factors

Exponent rule will be useful to remove grouping if the terms are containing exponents

Now combine the like terms using addition or subtraction

Then combine the constants

**Example 1**

Simply - 4*x*^{2} + 2*x*^{2}

(4 + 2)* x*^{2 }

**Answer: 6 x^{2}**

**Example 2**

3 + 3x [2(2x+4) +2)]

First, multiply the terms within brackets

3 + 3x [2(2x+4) +2)] = 3 + 3x [4x+8 +2] = **3 + 3x [4x+10]**

Now eliminate the parentheses by multiplying any number outside it

3 + 3x [4x+10] = 3 + 12*x*^{2 }+30x

**Answer - 12x ^{2}/3 + 30x/3 + 3/3 = 4 x ^{2} + 10x + 1**

**Example 3**

Simplify 2x + 3(x – 4)

2x + 3(x – 4) = 2*x* + 3*x* – 12

Answer - 2*x* + 3*x* – 12 = 5x - 12

**Example 4**

Simplify 3x – (2 – x)

3x – (2 – x) = 3*x* + (–1) [2 + (–x)]

= 3x + (–1) (2) + (–1) (–x)

= 3x – 2 +* x*

= 4x – 2

**Example 5**

Simplify 3(3x-1) + x((4x)/ (4)) + 5 – 2x

9x – 3 + x(x) + 5 – 2x

9x – 3 + x2 + 5 – 2x

x2 + (9x-2x) + (5-3)

**Answer = x2 + 7x + 2**
