1.5 Infinite Geometric Series
I am confident that if you have made it this far into unit 1, you have for sure understood the difference between arithmetic and geometric series. An infinite geometric series can be used for word problems and solved using formulas. Here are some videos that will definitely help you with your homework questions from your…
2.1: Polynomials
Polynomial: An expression that contains variables and coefficients ex. 5xy2 – 3x + 5y3 – 3 Term: A term consists of a variable and a coefficient ex. 5x Monomial: A polynomial containing only ‘1’ term ex. 5xy2 Binomial: A polynomial containing ‘2’ terms ex. 5xy2 – 3x Trinomial: A polynomial containing ‘3’ terms ex. 5xy2 – 3x + 5y3 …

6.3 Solving Linear Systems by Substitution
In the last section, we learned how to solve linear systems by addition. For this section, we’ll focus on solving using the substitution method. Like the name indicates, the substitution method requires you to find the value of one variable (either x or y) and then substitute it into the other equation, therefore solving the…
