This session has ended for today
The concept of binomial theorem and expansion is often tested on JAMB and other exams. so lets take a quick look into this topics.
Binomials  A polynomial is a series of terms. when there are only two terms the expression is called a binomial.
Trionomial A threetermed expression is called a trinomial.
The Expansion of (a + b)^{n} for any value of n is
(a + b)^{n} = a^{n} + na^{n1}b^{1} + n (n1) a^{n2}b^{2} / 2! + n(n1)(n2)a^{n3}/ 3! + ... +b^{n Can anyone provide solutions to the following; (a) Calculate the value of (2.01)3correct to 3 s.f., without using tables. (b) Expand ( 1 + 2x )4 (c) Find the third term in the expansion of (a + b)5 (d) Find the coefficient of x10 in the expansion of (2 + x)12 (e) In the expansion of (12x)3,write down the number of terms. Please give us your feedback after the session: http://goo.gl/forms/XVVy7QkNb5 }

@Adewale the correct answer to question (d) is 16896, since 1 2 combination 10 gives 66 x 2^8 = 16896

a (2+0.01) using bionomial theorem.. I have 8+0.12+0.0006+0.000001 =8.120601 approximately to 8.12
