This guide provides everything you need to know to succeed in Algebra 1, including clear explanations of all the key concepts, helpful examples, and practice problems. Whether you are struggling with a particular topic or simply want to brush up on your skills, this guide is a valuable resource.

## Algebra 1 Topics

Here is a brief overview of the main topics covered in Algebra 1:

• Linear equations and inequalities: Linear equations are equations in which the variables have a power of 1. Linear inequalities are similar to linear equations, but they have a less than or greater than sign instead of an equal sign.
• Systems of equations and inequalities: A system of equations is two or more equations that are solved together. A system of inequalities is similar to a system of equations, but it has less than or greater than signs instead of equal signs.
• Polynomials: Polynomials are expressions that contain variables and constants. Polynomials can be added, subtracted, multiplied, and divided.
• Quadratic functions: Quadratic functions are functions of the form $ax^2 + bx + c$, where $a$, $b$, and $c$ are constants. Quadratic functions can be graphed and analyzed using a variety of methods.
• Radical functions: Radical functions are functions that contain radicals. Radicals are symbols that represent the square root of a number. Radical functions can be graphed and analyzed using a variety of methods.
• Exponential and logarithmic functions: Exponential functions are functions of the form $a^x$, where $a$ is a positive constant and $x$ is any real number. Logarithmic functions are the inverse of exponential functions. Exponential and logarithmic functions can be graphed and analyzed using a variety of methods.
