The Binomial Theorem. Find each coefficient described. 1) Coefficient of x2 in expansion of ( 2 + x)5. 80. 3) Coefficient of x in expansion of ( x + 3)5. 405. 5) Coefficient of x3y2 in expansion of ( x − 3 y)5. 90.
10 cze 2024 · The binomial theorem is a formula for expanding binomial expressions of the form (x + y) n, where ‘x’ and ‘y’ are real numbers and n is a positive integer. The simplest binomial expression x + y with two unlike terms, ‘x’ and ‘y’, has its exponent 0, which gives a value of 1. (x + y) 0 = 1.
Exercise. 1 Expand the following expressions using binomial theorem. (a + b)3. (3x. 4)5. 4 (c) 5x3 y2. (d) 2x 4 1 x. 2 Expand the following expressions in ascending power of x up to the term x3. (a) (2x + 3)(x. 3)4. (b) (2 x + x2)6 Hint: You may consider (2. x + x2)6 as [2 + ( x + x2)]6.
In mathematics, the binomial theorem is an important formula giving the expansion of powers of sums. Its simplest version reads (x+y)n = Xn k=0 n k xkyn−k whenever n is any non-negative integer, the numbers n k = n! k!(n−k)! are the binomial coefficients, and n! denotes the factorial of n.
