Evaluating Square Roots of Perfect Squares

1. Evaluating Square Roots of Perfect Squares

Squares and square roots are inverse, or opposite, operations involving radicals. Learn how to determine the square root of perfect squares in this lesson.

Estimating Square Roots

2. Estimating Square Roots

Inverse operations are mathematical operations that undo each other. The square root is the inverse of the squared (or multiplying a number by itself) operation. There is an easy method for estimating the square root of a number, which you will learn in this lesson.

Simplifying Square Roots When not a Perfect Square

3. Simplifying Square Roots When not a Perfect Square

Numbers that are imperfect squares are those that, when evaluated, do not give solutions that are integers. The proper mathematical way to simplify these imperfect squares is discussed in this lesson.

Simplifying Expressions Containing Square Roots

4. Simplifying Expressions Containing Square Roots

In order to write radical expressions correctly, they have to be written in their simplest form. This lesson will show you how to simplify expressions containing numbers and variables inside a square root.

Discriminant: Definition & Explanation

5. Discriminant: Definition & Explanation

The discriminant helps you to solve quadratic equations. In this lesson, you will learn how to identify the discriminant and how to use it to help you find the number of solutions in a quadratic equation.

Principal Square Root: Definition & Example

6. Principal Square Root: Definition & Example

In this lesson, we will refresh our understanding of squaring a number and then explore the inverse operation called square root and define the principal root.

Square Root: Sign, Rules & Problems

7. Square Root: Sign, Rules & Problems

In this lesson, you will learn how to recognize square root notation. You will also learn properties of square roots and discover how to simplify expressions that include square roots.

The Square Root Property

8. The Square Root Property

In this lesson, we'll learn what the square root property is. We'll also look at how to use the square root property to solve quadratic equations and for which types of quadratic equations it can be used.

Adding Square Roots

9. Adding Square Roots

Square roots and radical expressions can be really difficult to add because they're often considered unlike terms and don't mix well. In this lesson, we'll look at how to simplify and solve problems involving adding square roots.

Subtracting Square Roots

10. Subtracting Square Roots

In this lesson, you'll learn how to subtract square roots. We'll explore different methods of square root subtraction to get either an exact or an approximate answer to the problem you're working on.
