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.

I'd just like to say that this really makes no sense how the sum of 7 and 3 =20 like honestly thsi subject makes me watn to throw myself down a flight of stairs

[Christaingrey]

Im sorry, but from where it leads that product of two numbers must be 7*-3?

[erinstacyamoin]

can someone answer this correctly ☺

(3x-4) (x+3) = x-8

i can't solve this bc all examples i see is something like "(3x-4)(x+3)=60" like that, thanks in advance!

I'm (35k^2 + 100k - 15)% sure that this guy just made up everything he said.
