Additional Resources

Algebra Basics

In order to succeed in Algebra 1, it is crucial that you're well versed in the basics of pre-algebra. These include dealing with negative numbers, understanding variables, and solving 1-step equations. Understanding integers and basic equations is the foundation needed to understand the basics of graphing, more advanced functions and polynomials, and the algebraic thinking skills necessary for algebra 1. Having trouble? Check out Fiveable's free study guides to learn all the basic algebraic concepts you need to crush Algebra 1.

Linear Equations

Linear equations are polynomials of degree 1. When graphed, as you may guess, they're a line! Linear functions are often the first and simplest functions you'll learn about in algebra, so understanding their forms and parts is essential for success. Luckily, Fiveable is here to help! Our free study guides and math support are here to help you study and succeed in algebra.

Quadratic Functions

Quadratic functions are often the biggest concepts in algebra classes, and for good reason. A quadratic function is a polynomial with a highest degree of 2, meaning somewhere in there an x will be squared. Unlike linear equations you may have seen, quadratics are curved when graphed and have a different rate of change. Of interest are the zeroes, or roots, of these equations and most of your time spent with them will be learning how to find said zeroes. These functions can be graphed, solved, factored, and more. Fiveable's free support will guide you to success in your algebra class!

Polynomials

Many of the functions you'll encounter in algebra are polynomials: functions with varying powers of x. This class of functions include quadratics, cubics, quartics, and more. All you need for a polynomial is x's raised to powers! You'll be required to learn how to solve, factor, and graph polynomials and use features of polynomials to solve problems. This includes polynomial division, the Fundamental Theorem of Algebra, and the Rational Root Theorem, which describe how polynomials can be solved. Fiveable's free guides will take you step by step through this crucial topic in your math class!
