What is Algebra?

Algebra is a branch of mathematics that deals with the study of variables and their relationships. It involves the use of symbols, equations, and formulas to solve problems and model real-world situations. Algebra is a fundamental subject that provides a powerful tool for problem-solving and critical thinking.

Basic Algebra Concepts

Before we dive into the cheat sheet, let's cover some basic algebra concepts. These include:

• Variables: Letters or symbols that represent unknown values.
• Constants: Numbers that don't change value.
• Coefficients: Numbers that multiply variables.
• Terms: Parts of an expression that are separated by plus or minus signs.
• Expressions: Groups of terms that are combined using mathematical operations.

Algebra Formulas and Equations

Now that we've covered the basics, let's move on to some key algebra formulas and equations. These include:

• Linear Equations: Equations in which the highest power of the variable is 1.
• Quadratic Equations: Equations in which the highest power of the variable is 2.
• Polynomial Equations: Equations in which the highest power of the variable is 3 or more.

Some common algebra formulas include:

• Slope-Intercept Form: y = mx + b
• Point-Slope Form: y - y1 = m(x - x1)
• Quadratic Formula: x = (-b ± √(b^2 - 4ac)) / 2a
