Chapter 11
11-1 Intro To Polynomials
To put these numbers in standard form you had to put the numbers in order from the highest exponent to lowest exponent. The highest exponent is the one that is the degree. The number in front of that variable is the leading coefficient.
11-2 Multiplying Polynomials
On these ones I like to use the box method. It makes it way easier for me when it's sorted out like that. It's just like foiling.
11-3 Factoring
The two numbers in this binomial must multiply to the constant, and add up to the number next to the variable.
11-4 The Factor Theorem
When you are finding zeros, zeros are always the number that will make that x equal zero, like shown.
11-6 Solving All Polynomial Equations
I find this one a little harder to do. I don't completely know how to do this. The x is supposed to equal zero though.
11-7 and 11-8 Finite Differences
You subtract the numbers down like shown until they are all the same number and then you can know the degree of it by counting the rows you made until they were all the same. Like in this one the degree is 3.
