Find eighth term in the expansion of x+y 13
WebObviously a binomial to the first power, the coefficients on a and b are just one and one. But when you square it, it would be a squared plus two ab plus b squared. If you take the third power, these are the coefficients-- third power. And to the fourth power, these are the coefficients. So let's write them down. WebAug 19, 2014 · Aug 19, 2014 The answer is: x5 − 5x4 + 10x3 − 10x2 +5x −1 When expanding, we consider the general form: (x +y)n. Recall that the first row of Pascal's Triangle is: (x +y)0. So for (x − 1)5, we are looking at the 6th row of Pascal's Triangle for the coefficients: ⎛ ⎜ ⎜ ⎜ ⎜ ⎜ ⎜ ⎜ ⎜ ⎜⎝ 1 1 1 1 2 1 1 3 3 1 1 4 6 4 1 1 5 10 10 5 1⎞ ⎟ ⎟ ⎟ …

Solution . The coefficient of x3y12 is positive because the exponent of y is even. That coefficient is 15C12. But 15C12 = 15C3, and so we have 15 · 14 · 13 1 · 2 · 3 = 455. The coefficient of x2y13, on the other hand, is negative because the exponent of y is odd. axf にじさんじWebfind the specified term for each binomial expansion.
