An example of a binomial coefficient is [latex]\left (\begin {gathered}5\\ 2\end {gathered}\right)=C\left (5,2\right)=10 [/latex]. A General Note: Binomial Coefficients. If [latex]n [/latex] and [latex]r [/latex] are integers greater than or equal to 0 with [latex]n\ge r [/latex], then the binomial coefficient is.

3 Ιαν 2018 · First example (click here): Expand (x+2)^4. 1. Apply the formula. a=x, b=2, n=4. (x+2)^4=\sum_ {i=0}^4\binom {4} {i}x^ (4-i)2^i. 2. Expand the summation and simplify. \sum_ {i=0}^4\binom {4} {i}x^ (4-i)2^i =\binom {4} {0} x^4∙2^0+\binom {4} {1} x^3∙2^1+\binom {4} {2} x^2∙2^2+\binom {4} {3} x^1 ∙2^3+\binom {4} {4} x^0∙2^4.
