Students will review:
This chapter helps students review the concepts in a square roots unit of a standard math course. Topics covered include:
- Evaluating square roots
- Estimating square roots
- Simplifying square roots
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
