 This topic introduces the student to the quadratic formula. This series of six lessons shows the student how to solve quadratic equations by using the quadratic formula. The student is taught how to handle cases that are not already written in standard form. The student is also introduced to the concept of irrational solutions to quadratic equations.

This lesson introduces the student to the quadratic formula. The student learns all of the parts that make up the quadratic formula.

### The Quadratic Formula: Solving Equations – Rational Solutions

In this lesson, the student learns how to solve quadratic equations using the quadratic formula. The student is introduced to the concept of quadratic equations having two real solutions, one real solution, or no real solutions.

### The Quadratic Formula: Solving Equations – Irrational Solutions

This lesson shows the student how to find the solutions to quadratic equations when the solution is irrational.

### The Quadratic Formula: Solving Equations – Missing Term

In this lesson, the student learns how to solve quadratic equations that are not written in standard form. The student learns to write the quadratic equation in standard form, first and then solve using the quadratic formula.

### The Quadratic Formula: All Types

In this lesson, the student sees all the examples previously taught in this topic.

### The Quadratic Formula: Solving Equations – Non-standard Form

This lesson introduces the student to quadratic equations that do not include all terms. The student learns that when a equals zero in the quadratic formula that the equation is linear, and that the student should solve this type of equation as a linear equation.
