Worked example (special cases) (Hinglish) | Binomial Theorem | Grade 11 | Math | Khan Academy

From the creator

In this video, we'll apply what we know about expansions of (a+b)^n and (a-b)^n to solve problems. We'll first expand (x + 1/x)^6 and then (2x-3)^6 by carefully replacing as and bs with appropriate values. Courses on Khan Academy are always 100% free. Start practicing—and saving your progress—now!
