Binomial expansion induction proof

WebWe can skip n=0 and 1, so next is the third row of pascal's triangle. 1 2 1 for n = 2. the x^2 term is the rightmost one here so we'll get 1 times the first term to the 0 power times the second term squared or 1*1^0* (x/5)^2 = x^2/25 so not here. 1 3 3 1 for n = 3. WebThat is, for each term in the expansion, the exponents of the x i must add up to n. Also, as with the binomial theorem, quantities of the form x 0 that appear are taken to equal 1 (even when x equals zero). In the case m = 2, this statement reduces to that of the binomial theorem. Example. The third power of the trinomial a + b + c is given by
