Algebra II on Khan Academy: Your studies in algebra 1 have built a solid foundation from which you can explore linear equations, inequalities, and functions. In algebra 2 we build upon that foundation and not only extend our knowledge of algebra 1, but slowly become capable of tackling the BIG questions of the universe. We'll again touch on systems of equations, inequalities, and functions...but we'll also address exponential and logarithmic functions, logarithms, imaginary and complex numbers, conic sections, and matrices. Don't let these big words intimidate you. We're on this journey with you!

About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

For free. For everyone. Forever. #YouCanLearnAnything

Correction:
Who ever you are thank you so much for putting theses videos together. Im prepping to retake my SATs as an adult and I'm having "oh Yeah" moments all day watching your videos. Thank you so much.
Just a little a correction for the end of this video, When you pulled out the calculator, you did 270*36 but you should have done 2700*36 which would have given you 97, 200

I Have a question here where I have to find the coefficient of x^6y^3 in the exapnsion (x+2y)^9 and by your method I am getting 10x^68y^3 but that isn't the answer. Real answer is 672. How ?
