(a+b+c)^3 expansion formula
(a+b+c)^3 expansion formula-In elementary algebra, the binomial theorem (or binomial expansion) describes the algebraic expansion of powers of a binomialAccording to the theorem, it is possible to expand the polynomial (x y) n into a sum involving terms of the form ax b y c, where the exponents b and c are nonnegative integers with b c = n, and the coefficient a of each term is a specific positive integer dependingQ = (x 2;y 2) you can obtain the following information 1The distance between

For example, when n = 5, each term in the expansion of (a b) 5 will look like this a 5 − k b k k will successively take on the values 0 through 5 (a b) 5 = a 5 a 4 b a 3 b 2 a 2 b 3 ab 4 b 5 Note Each lower index is the exponent of b The first term has k = 0 because in the first term, b appears as b 0, which is 1Of course, the power of Taylor's Formula is that we can use it to obtain higherorder poly 3 f (a,b) = 3x fxxx 3x yfxxy 3xy2fxyy y3fyyy It turns out that you can easily get the coecients of the expansion from Pascal's Triangle 1 11 121 1331Related Topics Mathematics Mathematical rules and laws numbers, areas, volumes, exponents, trigonometric functions and more ;
