This means that the binomial expansion will consist of terms related to odd numbers. This is called the general term, because by giving different values to r we can determine all terms of the expansion. Question: 3. b) Hence, deduce an expression in terms of a and b for a + b 4 + a - b 4 . Let us now look at the most frequently used terms with the binomial theorem. The binomial theorem states a formula for expressing the powers of sums. There are various important terms such as general term, middle, term, etc.

For Example (a+b)5 is a binomial. Let's say if you expand (x+y), therefore, the middle term results in the form the (2 / 2 + 1) which is equal to 2nd term. ( x + y) 0 = 1 ( x + y) 1 = x + y ( x + y) 2 = x 2 + 2 x y + y 2. and we can easily expand. It is usually represented as Tr+1. This calculators lets you calculate expansion (also: series) of a binomial.
