To solve quadratic equations that are unfactorable, you'll need to know how to use the quadratic formula, and this quiz/worksheet combo will allow you to better understand this formula. These practice questions will test you on the characteristics of the quadratic formula and solving quadratic equations.

In these assessments, you'll be tested on:

- The correct version of the quadratic formula
- Identifying the value of a variable in the quadratic equation
- Positive and negative discriminants
- Using the quadratic formula to solve and find roots of equations

**Reading comprehension**- ensure that you draw the pertinent information on using the quadratic formula from the related lesson**Problem solving**- use your acquired knowledge to solve practice quadratic equations using the quadratic formula**Distinguishing differences**- compare and contrast topics from the lesson, such as the separate ways to solve factorable and unfactorable equations

You should also read the related lesson called How to Use the Quadratic Formula to Solve a Quadratic Equation. This lesson covers the following objectives:

- Define the quadratic formula as a method used to solve equations that are unfactorable
- Define discriminants
- Understand how to define the roots and solutions of quadratic equations
- Understand how to identify the value of a variable and substitute those values into the quadratic formula
