Let us multiply ab by itself using Polynomial Multiplication (ab) (ab) = a2 2ab b2 Now take that result and multiply by ab again (a 2 2ab b 2 ) (ab) = a3 3a2b 3ab2 b3 And again (a 3 3a 2 b 3ab 2 b 3 ) (ab) = a4 4a3b 6a2b2 4ab3 b44 Binomial Expansions 41 Pascal's riTangle The expansion of (ax)2 is (ax)2 = a2 2axx2 Hence, (ax)3 = (ax)(ax)2 = (ax)(a2 2axx2) = a3 (12)a 2x(21)ax x 3= a3 3a2x3ax2 x urther,F (ax)4 = (ax)(ax)4 = (ax)(a3 3a2x3ax2 x3) = a4 (13)a3x(33)a2x2 (31)ax3 x4 = a4 4a3x6a2x2 4ax3 x4 In general we see that the coe cients of (a x)n come from the nth row of Pascal'sWhat are the coefficients for the binomial expansion of (a b)3?

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
