What is the formula for binomial expansion
What is the formula for binomial expansion-2903 · Definition binomial A binomial is an algebraic expression containing 2 terms For example, (x y) is a binomial We sometimes need to expand binomials as follows (a b) 0 = 1(a b) 1 = a b(a b) 2 = a 2 2ab b 2(a b) 3 = a 3 3a 2 b 3ab 2 b 3(a b) 4 = a 4 4a 3 b 6a 2 b 2 4ab 3 b 4(a b) 5 = a 5 5a 4 b 10a 3 b 2 10a 2 b 3 5ab 4 b 5Clearly, · Binomial expression is an algebraic expression with two terms only, eg 4x 2 9 When such terms are needed to expand to any large power or index say n, then it requires a method to solve it Therefore, a theorem called Binomial Theorem is introduced which is an efficient way to expand or to multiply a binomial expressionBinomial Theorem is defined as the

Use the Binomial Theorem to Expand a Binomial We are now ready to use the alternate method of expanding binomials The Binomial Theorem uses the same pattern for the variables, but uses the binomial coefficient for the coefficient of each term( 4 k)!The binomial theorem revisited The binomial theorem, as stated in the previous section, was only given for n as a whole positive number We can now find the binomial expansion for (1 x) n for all values of n using the Maclaurin series f(x) = (1 x)n f′ ( x) = n (1 x) n−1 f ″ ( x) = n ( n − 1) (1 x

Sounds like we want to use pascal's triangle and keep track of the x^2 term We 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⋅ ( X) 4 k ⋅ ( Y(MIDDLE SCHOOL MATH) For a school dance, a section of the gym, in the shape of a trapezoid, has
