We’ll now progress beyond the world of purely linear expressions and equations and enter the world of quadratics (and more generally polynomials). Here we’ll learn to factor expression that have powers of 2 in them and solve quadratic equations. We’ll also learn to manipulate more general polynomial expressions.
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, computing, history, art history, economics, and more, including K-14 and test preparation (SAT, Praxis, LSAT) content. We focus on skill mastery to help learners establish strong foundations, so there's no limit to what they can learn next!
