In the Algebra 1 tutorial videos, students gain a solid foundation learning linear equations, inequalities, and functions. These Algebra 2 videos from Khan Academy build upon that and extend to tackling bigger questions of the universe. They start with systems of equations, inequalities, and functions, and then address and demonstrate exponential and logarithmic functions, logarithms, imaginary and complex numbers, conic sections, and matrices.
These algebra videos will help students get up to speed and master this most important area of mathematics. They are all together in this downloadable zip file that is 874 mb in size. After unzipping it, you’ll see the videos in a folder named “308 Algebra II Videos by Khan Academy”. Just double click on the index.html file to start viewing them, you’ll see the screen shot below in your browser, which is the top-level table of contents page. Once the zip file is downloaded and unzipped, no internet connection is needed to view them.

Topics Covered By These 308 Algebra 2 Videos:
Systems of equations and inequalities – 31 videos
What happens when we have many variables but also many constraints.
Functions and their graphs – 62 videos
Revisiting what a function is and how we can define and visualize one.
Polynomial and rational functions – 83 videos
Exploring quadratics and higher degree polynomials. Also in-depth look at rational functions.
Rational expressions – 35 videos
You have probably been wondering whether our powers of algebraic problem solving break down if we divide by the variable or we have entire expressions in denominator of a fraction. In this topic, you’ll learn how to interpret and manipulate rational expressions.
Exponential and logarithmic functions – 23 videos
A look at exponential and logarithmic functions including many of their properties and graphs.
Logarithms – 27 videos
Now you can think about what exponent you have to raise a number to to get another number. Yes, I agree–unstoppable fun for the whole family. Logarithms are used everywhere (including to measure earthquakes and sound).
Imaginary and complex numbers – 14 videos
Understanding and solving equations with imaginary numbers.
Conic sections – 25 videos
A detailed look at shapes that are prevalent in science: conic sections
Matrices – 8 videos
