expand (2x-3y)^6

expand

(2 x - 3 y)^{6}

64 x^{6} - 576 x^{5} y + 2160 x^{4} y^{2} - 4320 x^{3} y^{3} + 4860 x^{2} y^{4} - 2916 x y^{5} + 729 y^{6}

Solution steps

(2 x - 3 y)^{6}

Apply binomial theorem:

(a + b)^{n} = i = 0 \sum n (i n) a^{(n - i)} b^{i}

a = 2 x, b = - 3 y

= i = 0 \sum 6 (i 6) (2 x)^{(6 - i)} (- 3 y)^{i}

Expand summation
