expand (x-3)^{14}

Solution

expand

(x - 3)^{14}

Solution

x^{14} - 42 x^{13} + 819 x^{12} - 9828 x^{11} + 81081 x^{10} - 486486 x^{9} + 2189187 x^{8} - 7505784 x^{7} + 19702683 x^{6} - 39405366 x^{5} + 59108049 x^{4} - 64481508 x^{3} + 48361131 x^{2} - 22320522 x + 4782969

Solution steps

(x - 3)^{14}

Apply binomial theorem:

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

a = x, b = - 3

= i = 0 \sum 14 (i 14) x^{(14 - i)} (- 3)^{i}

Expand summation
