2.2 Multiplying Polynomials
General Rules: (a + b)2 = a2 + 2ab + b2 (a – b)2 = a2 – 2ab + b2 (a – b)(a + b) = a2 – b2 Multiplying using FOIL Calculating the area of a shape Other multiplication problems Have any questions? Leave them in the comments below!
2.1 Classifying Polynomials
Polynomials can be confusing if you don’t know your terminology. For this section, we’ll cover the terms you need to know, and a basic guide to multiplying polynomials. Check out the links below for an explanation! Some Terms You Should Know: Term: a number or a product of a number with one or more variables.…
1.6 Irrational Numbers
I know, we’ve done a lot of rational and irrational work in this chapter – last one, I promise. In this section, we’ll be simplifying square roots and cube roots, as well as changing forms from mixed roots to entire roots. Confused? Here are some things that you need to know: How to simplify square…
1.5 Exponential Notation
If you’ve heard of scientific notation, then you know what exponential notation is: they’re both ways of expressing really large numbers. For instance, you could write 256 as 2*2*2*2*2*2*2*2 or 2^8 (exponential notation). Here are some resources to help you figure out exponential notation: Website: https://saylordotorg.github.io/text_intermediate-algebra/s04-05-rules-of-exponents-and-scienti.html Videos:
1.4 Rational and Irrational Numbers

1.3 Squares and Square Roots
Squares and square roots may seem complicated, but they’re actually quite easy once you get the hang of it. Terms You Should Know: Squares: to raise a number to the second power; i.e. to multiply a number by itself twice Square Roots: a number that, when multiplied by itself, gives the square (the square root…
1.2 GCF (Greatest Common Factor) and LCM (Least Common Multiple)
A key concept in finding the GCF and LCM is factoring. This post will cover prime factorization, as well as two different ways of finding the GCF and LCM: factor trees and continuous division. Additionally, you should know the following terms: GCF: Greatest Common Factor LCM: Least Common Multiple Prime Numbers: a whole number that…
1.1 Number Systems
Number Systems: a way of grouping certain numbers together, based on what “type” of number they are: natural, whole, integers, rational, irrational or real numbers.
