Write the formula / expansion for (a b)3 (a b) 3 = a 3 3a 2 b 3ab 2 b 3 Substitute x for a and 1 for b (x 1) 3 = x 3 3 (x 2 ) (1) 3 (x) (1 2) 1 3 (x 1) 3 = x 3 3x 2 3 (x) (1) 1 (x 1) 3 = x 3 3x 2 3x 1 So, the expansion of (x 1)3 is x 3 3x 2 3x 1In elementary algebra, the binomial theorem describes the algebraic expansion of powers of a binomial According to the theorem, it is possible to expand the polynomial n into a sum involving terms of the form axbyc, where the exponents b and c are nonnegative integers with b c = n, and the coefficient a of each term is a specific positive integer depending on n and b For example, 4 = x 4 4 x 3 y 6 x 2 y 2 4 x y 3 y 4 {\displaystyle ^{4}=x^{4}4x^{3}y6x^{2}y^{2}4xy^{3}y^{4}} TheExpansion of (a b) 3 ∴ (a b) 3 = (a b)(a b)(a b) = (a b)(a b) 2 = (a b)(a 2 2ab b 2) = a(a 2 2ab b 2) b(a 2 2ab b 2) = a 3 2a 2 b ab 2 a 2 b 2ab 2 b 3 = a 3 3a 2 b 3ab 2 b 3 ∴ (a b) 3 = a 3 3a 2 b 3ab 2 b 3
A few simple expansion of (a b) to different powers (a b)2 = a2 2ab b2 (a b)3 = a3 3a2b 3ab2 b3 (a b)4 = a4 4a3b 6a2b2 4ab3 b4 You may begin to see a pattern in the coefficients They come from Pascal's Triangle 1 1 1 1 2 1 (a b)2#_3C_3 = (3!)/((33)!(3!)) = (3!)/(0!*3!) = 1# Note #(ab)^3 = (a (b))^3# Substitute into the Binomial expansion formula, let #x = a# and #y = b# #(ab)^3 = a^3 3a^2(b)^1 3a(b)^2(b)^3# #= a^3 3a^2b 3ab^2 b^3#So (a b)¹ = a b (a b)² = a² 2ab b² (a b)³ = a³ 3a²b 3b²a b³ You should notice that the coefficients of (the numbers before) a and b are 1 1 1 2 1 1 3 3 1 If you continued expanding the brackets for higher powers, you would find that the sequence continues 1 4 6 4 1
If we want to expand (ab)3 we select the coefficients from the row of the triangle beginning 1,3 these are 1,3,3,1 We can immediately write down the expansion by remembering that for each new term we decrease the power of a, this time starting with 3, and increase the power of b So (ab) 3= 1a 3a2b3ab2 1b3 which we would normally write as justWe can do this if you know the Binomial Theorem But if you don't know what it is or how to use it you can do the expansion on your own (ab)^3 = (ab)(ab)(ab) This becomes (ab)(ab)^2 =O 1, 4, 6, 4, 1 O 1,1 O 1, 2,1 O 1,3,3, 1 2 See answers esbeydeeromero esbeydeeromero The fourth option I got that last time happy244 happy244 Answer D Stepbystep explanation New questions in Mathematics
