Polynomials 03: Adding
Polynomials 03: Adding
 |
Adding polynomials is pretty much the same as simplifying them in the last lesson. All of the like terms can be combined.
For instance if we needed to add 4x2-3+7x and 5x-x2+7+2x3 it would look like this (4x2-3+7x)+(5x-x2+7+2x3). All of the terms can then be put in order starting with the highest exponent and alphabetically resulting in 2x3+4x2-x2+7x+5x+7-3. Like terms can be combined to give a final polynomial of 2x3+3x2+12x+4.
