**Linear equations and inequalities**

A linear equation is an equation of the form `ax + b = y`

, where `a`

and `b`

are constants and `x`

and `y`

are variables. A linear inequality is an inequality of the form `ax + b < y`

, `ax + b > y`

, `ax + b ≤ y`

, or `ax + b ≥ y`

.

To solve a linear equation, you can use the following steps:

- Isolate the variable
`x`

by adding or subtracting any constants from both sides of the equation. - Divide both sides of the equation by the coefficient of
`x`

. - Simplify the answer.

To solve a linear inequality, you can use the following steps:

- Isolate the variable
`x`

by adding or subtracting any constants from both sides of the inequality. - Divide both sides of the inequality by the coefficient of
`x`

. - Determine the sign of the inequality. If the coefficient of
`x`

is positive, then the inequality sign remains the same. If the coefficient of`x`

is negative, then the inequality sign is reversed. - Graph the solution on a number line.

**Systems of equations**

A system of equations is a set of two or more equations that have the same variables.

There are two main methods for solving systems of equations: elimination and substitution.

To solve a system of equations by elimination, you can use the following steps:

- Multiply one or both of the equations by a constant so that one of the coefficients of the variables is the same in both equations.
- Add or subtract the equations to eliminate one of the variables.
- Solve the remaining equation for the remaining variable.
- Substitute the value you found for the variable back into one of the original equations to solve for the other variable.

To solve a system of equations by substitution, you can use the following steps:

- Solve one of the equations for one of the variables.
- Substitute the expression you found for the variable into the other equation.
- Solve the resulting equation for the remaining variable.
- Substitute the value you found for the variable back into the equation you solved in step 1 to solve for the other variable.

**Polynomials**

A polynomial is an expression that consists of variables and coefficients, and the only operations involved are addition, subtraction, multiplication, and exponentiation to non-negative integer powers.

To add, subtract, and multiply polynomials, you can use the following rules:

- Like terms can be added or subtracted.
- To multiply two polynomials, you can use the distributive property.

To factor polynomials, you can use a variety of methods, such as common factoring **continued article:**

**Quadratic equations and functions**

A quadratic equation is an equation of the form `ax² + bx + c = 0`

, where `a`

, `b`

, and `c`

are constants and `x`

is a variable.

To solve a quadratic equation, you can use the following methods:

- Factoring: If the quadratic equation can be factored, then you can solve for
`x`

by setting each factor equal to zero and solving the resulting linear equations. - Quadratic formula: If the quadratic equation cannot be factored, then you can use the quadratic formula to solve for
`x`

:

```
x = (-b ± √(b² - 4ac)) / 2a
```

where `a`

, `b`

, and `c`

are the coefficients of the quadratic equation.

**Other Algebra 1 topics**

In addition to the topics covered above, Algebra 1 also typically covers the following topics:

- Radical expressions: Radical expressions are expressions that contain radicals, which are square roots, cube roots, and other roots of numbers.
- Rational expressions: Rational expressions are expressions that contain fractions.
- Exponential functions: Exponential functions are functions of the form
`f(x) = a^x`

, where`a`

is a positive constant and`x`

is a variable. - Logarithmic functions: Logarithmic functions are the inverse of exponential functions.

**Conclusion**

Algebra 1 is a foundational math course that covers a variety of important topics. By understanding the concepts and practicing solving problems, you can set yourself up for success in future math courses and in other areas of your life.
