Factorials To Binomial Theorem
In the expansion, x will be the first term and −y will be the second Thus, the expression looks like this (1 ⋅ ( − y)5 ⋅ x0) (5 ⋅ ( −y)4 ⋅ x1) (10 ⋅ ( − y)3 ⋅ x2) (10⋅ ( − y)4 ⋅ x3) (5 ⋅ ( −y)5 ⋅ x4) (1 ⋅ ( −y)0 ⋅ x5) For each term from Pascal's Triangle, the exponent of the first term, x, increases by 1, while the exponent of the second term, −y, decreases by 1 Click here 👆 to get an answer to your question ️ Expand the following (1/x y/3)^3 niva787 niva787 Math Secondary School answered Expand the following (1/x y/3)^3 2 See answers Advertisement Advertisement asifa127 asifa127 (1/xy/3)^3 (ab)^3 formula (1/x)^3A 3 − b 3 = ( a − b) ( a 2 a b b 2) Then with the choice a = ( x y) 1 / 2, b = ( x − y) 1 / 2, and in the case x ≥ y , we can also write x y = a 2, x − y = b 2;
According to Pascal's Triangle, the coefficients for (xy)^3 are 1, 3, 3, 1 This means that the expansion of (xy)^3 will be R^2 at SCCExpand (xy)^3 (x y)3 ( x y) 3 Use the Binomial Theorem x3 3x2y3xy2 y3 x 3 3 x 2 y 3 x y 2 y 3 Multiply the result by the last two brackets ( x 2 y 2 − 2 x y) ( x − y) = x 3 − x 2 y x y 2 − y 3 − 2 x 2 y 2 x y 2 ⇒ x 3 − y 3 − 3 x 2 y 3 x y 2 Always expand each term in the bracket by all the other terms in the other brackets, but never multiply two or more terms in the same bracket This is helpful 0
