Introduction

In algebra, simplifying expressions is a crucial step in solving equations and inequalities. One of the most effective ways to simplify expressions is by using a vertical format, also known as a column format. This format allows us to line up like terms and perform operations easily, making it an essential tool for any math student or professional. In this article, we will explore the concept of simplifying expressions using a vertical format and provide a step-by-step guide on how to do it.

What is a Vertical Format?

A vertical format is a way of writing algebraic expressions where the terms are lined up in columns. This format is particularly useful when we have multiple terms with the same variable and exponent. By lining up these terms, we can easily add or subtract them, making it easier to simplify the expression.

How to Simplify using a Vertical Format

To simplify an expression using a vertical format, follow these steps:

Step 1: Write the Expression

Write the expression in a vertical format, with each term on a new line. Make sure to line up the like terms, i.e., the terms with the same variable and exponent.

Step 2: Combine Like Terms

Combine the like terms by adding or subtracting their coefficients. Make sure to keep the same variable and exponent for each term.

Step 3: Simplify the Expression

Simplify the expression by combining the like terms and eliminating any unnecessary terms.

Example: Simplifying an Expression using a Vertical Format

Let's consider the following expression:

{ \begin{array}{r} -5x^3 + 4x^2 - 7x + 7 \\ + \ 5x^3 - 9x^2 + 9x + 9 \\ \hline \end{array} \}

To simplify this expression using a vertical format, follow these steps:

Step 1: Write the Expression

Write the expression in a vertical format, with each term on a new line.

Step 2: Combine Like Terms

Combine the like terms by adding or subtracting their coefficients.

Term	Coefficient
$-5x^3$	-5
$+5x^3$	5
$4x^2$	4
$-9x^2$	-9
$-7x$	-7
$9x$	9
$7$	7
$9$	9

Step 3: Simplify the Expression

Simplify the expression by combining the like terms and eliminating any unnecessary terms.

Term	Coefficient
$x^3$	0
$x^2$	-5
$x$	2
Constant	16

The simplified expression is:

$-5x^2 + 2x + 16$
