What is the method given in this article for adding several polynomials?

No options given. But there are two methods of adding polynomials; The horizontal method, and the vertical method.

Step-by-step explanation:

The options are not stated here. However, there are two methods of adding polynomials; The horizontal method, and the vertical method.

Example: Suppose we want to add the polynomials (3x³ + 5x² + 56) + (16x² + 3x) + (4x³ + 4)

Horizontal method

(3x³ + 5x² + 56) + (16x² + 3x) + (4x³ + 4)

First collect the like terms

3x³ + 4x³ + 5x² + 16x² + 3x + 56 + 4

= 7x³ + 21x² + 3x + 60

Vertical method

3x³ + 5x² + ... 56

+ ... 16x² + 3x

4x³ + ... 4

...

7x³ + 21x² + 3x + 60

These two methods both yield the same results.
