(x y)^3 expansion 325256

A commonly misunderstood topic in precalculus is the expansion of binomials In this video we take a look at what the terminology means, make sense of theMultiply both sides of the equation by 3 x y, the least common multiple of x y, 3 Use the distributive property to multiply 3 by 2x^ {2}5y^ {2} Use the distributive property to multiply 3 by 2 x 2 − 5 y 2 Subtract xy from both sides Subtract x y from both sidesBinomial Expansions Binomial Expansions Notice that (x y) 0 = 1 (x y) 2 = x 2 2xy y 2 (x y) 3 = x 3 3x 3 y 3xy 2 y 3 (x y) 4 = x 4 4x 3 y 6x 2 y 2 4xy 3 y 4 Notice that the powers are descending in x and ascending in yAlthough FOILing is one way to solve these problems, there is a much easier way

 Hi Heureka, I am wondering if it can still be done easily if it is made more complicated ?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 positiveExpansion of ( )2 3− x 10 b) Use the first three terms in the binomial expansion of ( )2 3− x 10, with a suitable value for x, to find an approximation for 197 10 c) Use the answer of part (b) to estimate, correct to 2 significant figures, the value of 394 10

9 5 The Binomial Theorem

The expansion is given by the following formula $$$ \left(a b\right)^{n} = \sum_{k=0}^{n} {\binom{n}{k}} a^{n k} b^{k} $$$, where $$$ {\binom{n}{k}} = \frac{nFirst week only $499!We know the algebraic expansion of (x y) 3 Rearranging the terms in the expansion, we will get our identity for x 3 y 3 Thus, we have verified our identity mathematically Again, if we replace x with − y in the expression, we have This identity can also be expressed as, This is the required standard algebraic identity In the expression, if we replace y with (− y), we will get the
