How do you expand (x-y)^3? Socratic

WebSep 23, 2024 · Thus, the first appears ( n 0) times, the second ( n 1) times, the third ( n 2) times, and in general the r + 1 th appears. ( n r) times. These are the coefficients of the terms of the expansion. So, when we expand ( x + y) n, first we have all x 's, so that the first term is x n. Then we have one y. Web( X) 4 - 1 ⋅ ( Y) 1 + 4!

WebHint: Note that x is even (work modulo 3). Let x=2s. We are solving 3^y=(z-2^s)(z+2^s). Each term on the right is a power of 3. But their difference is a power of 2, and we are down ... WebJul 31, 2016 · The first, second and third terms of (x + 3)12 are: (12 0)x12 = x12. (12 1)3x11 = 12 1 ⋅ 3x11 = 36x11. (12 2)32x10 = 12⋅ 11 2 ⋅ 1 ⋅ 9x10 = 66 ⋅ 9x10 = 594x10. If you were looking for more or later terms in the expansion, then it might be easier to pick them out from the appropriate row of Pascal's triangle. WebExpand Using the Binomial Theorem (x-y)^3.
