"Fractional Equations" Fractional PPT courseware

Description

"Fractional Equations" Fractional PPT courseware

learning target:

1. Understand the concepts of integral equations, fractional equations and root augmentation;

2. Master the solutions to fractional equations that can be transformed into linear equations of one variable and quadratic equations of one variable;

3. Understand the reasons why fractional equations have increased roots and master the method of root verification.

Definition of rooting

Root augmentation: roots that appear in the process of removing the denominator and converting a fractional equation into an integer equation that are not suitable for the original equation.

the root that makes the denominator equal to zero

The reason: after both sides of the fractional equation are multiplied by a zero factor, the roots obtained are the roots of the integral equation, not the roots of the fractional equation.

think:

What is the difference between root testing for solving fractional equations and root testing for solving linear and quadratic equations?

Summary:

1. The concepts of integral equations and fractional equations;

2. Solve fractional equations; (pay attention to inspection)

3. Root augmentation and the causes of root augmentation;

4. Understand the thinking methods of mathematical transformation.
