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…
1.3 Radical Operations
What is a radical? A radical involved roots, more specifically, an expression/ equation that uses a root. Key points/ summary of section 1.3… nth Root If a and b are real numbers and n is a positive integer, then x is an nth root of a if x^n = a Absolute values The absolute value…
1.2 Factoring ax2+ bx+ c
ax2 + bx + c is a polynomial that has a coefficient of a, and a does not equal to 1. Continuing from what you learned in section 1.1, in section 1.2, we will be factoring polynomials with a coefficient of a, which can be any number but 1. Key points and skills you will need to know for…
1.1 Factoring x2 + bx + c
x2 + bx + c is a polynomial that can be factored using various methods. In math 10, you learned how to factor… By factoring our the GCF Bottoms up method (the ac method) FOIL Decomposition The grouping method Perfect Square trinomial Difference of Squares trinominal Here is a quick summary of the steps you should take in order…
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.
