Hi, I'm Sal Khan, founder of the not-for-profit Khan Academy, and I have some very exciting news. The data is in from our first year of the partnership between us and the College Board around KH Academy being the official practice for the SAT.

What we're seeing is students who spend an average of 20 hours of practice on KH Academy are seeing roughly a 115-point gain between the PSAT and the SAT. To put that into perspective, that's roughly twice the point gain that students typically see between the PSAT and the SAT.

What's especially heartening is that we're seeing that gain be consistent across gender, race, and socioeconomic groups. This makes us feel really good—not just from the KH Academy's point of view or the College Board's point of view, but just in the overall theme of being able to help level the playing field.

Students take the PSAT; they can sync those accounts with the KH Academy. The KH Academy software then has the information necessary to essentially do weak-point training. It knows where you need practice, not just in math but in reading and writing as well, and you get that practice so that you can put your best foot forward, not just on the SAT, but to be optimally prepared for college and for life.

So this is exciting news. It's also just the beginning, and we hope to work with all of you—students, parents, teachers—to further level the playing field for college and life access.

Let’s say that we have the polynomial p of x, and when expressed in factored form, it is (x + 2)(2x - 3)(x - 4). What we’re going to do in this video is use our knowledge of the roots of this polynomial to think about intervals where this polynomial would…

Finding measures using rigid transformations

We are told that triangle ABC, which is right over here, is reflected across line L. So it’s reflected across the line L right over here to get to triangle A prime, B prime, C prime. Fair enough! So based on that, they’re going to ask us some questions, …
