Description

"Mixed Operations of Quadratic Radicals" PPT courseware

To perform addition and subtraction of quadratic radicals, what characteristics do they have to be combined?

(1) Name three similar quadratic radicals of 2√5;

(2) Try to cite a group of similar quadratic radicals.

(3) Which of the following equations are quadratic radicals of the same type?

calculate

1. Pay attention to the order of operations

2. Use the law of operations

The operational laws of integer operations are still applicable to the operation of quadratic radicals.

As can be seen from Example 2, the multiplication of quadratic radicals is similar to the multiplication of polynomials.

We can use the multiplication formula of polynomials to perform simple operations on the multiplication of certain quadratic radicals.

Inspired by the result of question (1) in Example 3, multiply both the numerator and denominator by (√2+1) to make the denominator become 1.
