You can test for inequality but not for equality.
You can take different values of the independent variable or argument of the expression (usually denoted by x), and calculate the dependent variable or the value of the expression (usually denoted by y). These can be tabulated or shown on a graph. If the y-values for the same x-values are different, then the two expressions are different. But even if they all match perfectly, you cannot say that they are equivalent because there could be other x-values - which you did not test - for which the y-values are different.
For example, consider
f(x) = x^2 + 4
and
g(x) = x^3 - 3x^2 - 5x + 4
then f(-1) = 5 = g(-1)
f(0) = 4 = g(0)
and f(5) = 29 = g(5)
but for any other integer value of x, the values of the two expressions are different. However, your test did not pick that up.
You could increase the number of points tested but there will be other expressions such that the two can match at any number of selected points and still be different elsewhere.
What else can I help you with?
What do you do in Algebra?
Solve for variables using equations graphs and tables. There is also a lot of substituting
What is a disadvantage to using tables?
it is often difficult to solve complicated problems alone
How do you solve a system of equations approximately using graphs and tables?
To solve a system of equations approximately using graphs and tables, you can start by graphing each equation on the same coordinate plane. The point where the graphs intersect represents the approximate solution to the system. Alternatively, you can create a table of values for each equation, identifying corresponding outputs for a range of inputs, and then look for common values that indicate where the equations are equal. This visual and numerical approach helps to estimate the solution without exact calculations.
How do you do representing rates with tables and graphs?
To represent rates using tables, organize the data in rows and columns, where one column typically represents the independent variable (like time) and the other shows the dependent variable (like distance or cost). For graphs, plot the independent variable on the x-axis and the dependent variable on the y-axis, using points to indicate data values and connecting them to illustrate trends. This visual representation makes it easier to analyze the relationship between the two variables and understand how rates change over time or across different scenarios.
What are the steps for rewriting expressions?
There are a few steps to rewriting expressions. The steps of rewriting expressions are finding the value of the letter and then using the common factor.

Definition of numerical data?
Numerical data is data measured or identified on a numerical scale. Numerical can be analyzed using statistical methods, and results can be displayed using tables, charts, histograms, and graphs.

What are the disadvantages of using graphs?
I like graphs, no disadvantages.
How do you interpret non prose form?
You can interpret non-prose using visual aids. You can use charts, graphs, and tables to compare and contrast data from compositions that use prose.
How are circle graphs line graphs and bar graphs different?
a circle graph is in a circular form and represents your data using pieces inside of itbar graphs represents data using bars
How does scientists organize data?
Scientists organize data using various methods such as creating tables, graphs, charts, and databases. They may also use statistical analysis to identify patterns, trends, and relationships in the data. Proper organization of data helps scientists to draw meaningful conclusions and make informed decisions based on their research.
What methods can be used to find the equivalence point in a titration experiment?
In a titration experiment, the equivalence point can be found using methods such as using a pH meter to detect a sudden change in pH, using an indicator that changes color at the equivalence point, or using a titration curve to identify the point of neutralization.
What is an advantage of using graphs and diagrams?
An advantage to using graphs and diagrams in presentations is that it is easy for your audience to see what you are describing. Graphs and diagrams help get your point across.
Feature of rdbms?
It stores data in tables. Tables have rows and column. These tables are created using SQL. And data from these tables are also retrieved using SQL
