Web1. The coefficient of x 2 in the expansion of ( 1 + x 5) n, where n is a positive integer, is 3 5 . ( i) Find the value of n. ( i i) Using this value of n, find the term independent of x in the expansion of ( 1 + x 5) n × ( 2 − 3 x) 2. For part ( i) I used the Binomial theorem and got the result where n = 6.

HOW TO FIND THE CONSTANT TERM IN A BINOMIAL EXPANSION …

WebAboutTranscript. The Binomial theorem tells us how to expand expressions of the form (a+b)ⁿ, for example, (x+y)⁷. The larger the power is, the harder it is to expand … WebIndependent Term In the expansion of x I whcrc x O, thc middle , i.e., (n + l) temn, as 2n is even. term IS 2n cnx It is given by n Cn (constant) This term is called term independent of x or the constant term. So, Independent term IS the term In binomial expansion whose power of x is zero. cybercrime the guardian

A-Math Binomial Expansion: Finding Term Independent …

WebHence, 𝑛 = 1 2 or 𝑛 = − 1 1. The binomial theorem only applies for the expansion of a binomial raised to a positive integer power. Therefore, 𝑛 must be a positive integer, so we can discard the negative solution and hence 𝑛 = 1 2. We can now use this to find the middle term of the expansion. WebThe general term or (r + 1)th term in the expansion is given by T r + 1 = nC r an–r br 8.1.3 Some important observations 1. The total number of terms in the binomial expansion of (a + b)n is n + 1, i.e. one more than the exponent n. 2. In the expansion, the first term is raised to the power of the binomial and in each WebClick here👆to get an answer to your question ️ The term independent of x in the binomial expansion of ( 1 - 1/x + 3x^5 ) ( 2x^2 - 1/x )^8 is.
