expand (4-x/(16))^6(x-1/x)^2

expand

(4 - \frac{x}{16})^{6} (x - \frac{1}{x})^{2}

\frac{4096 ( x ^{4} - 2 x ^{2} + 1 )}{x ^{2}} - \frac{384 ( x ^{4} - 2 x ^{2} + 1 )}{x} + 15 x^{4} - 30 x^{2} + 15 - \frac{5 ( x ^{4} - 2 x ^{2} + 1 ) x}{16} + \frac{15 ( x ^{4} - 2 x ^{2} + 1 ) x ^{2}}{4096} - \frac{3 ( x ^{4} - 2 x ^{2} + 1 ) x ^{3}}{131072} + \frac{( x ^{4} - 2 x ^{2} + 1 ) x ^{4}}{16777216}

Solution steps

(4 - \frac{x}{16})^{6} (x - \frac{1}{x})^{2}

Expand

(x - \frac{1}{x})^{2} : \frac{x ^{4} - 2 x ^{2} + 1}{x ^{2}}

= (4 - \frac{x}{16})^{6} \frac{x ^{4} - 2 x ^{2} + 1}{x ^{2}}

= \frac{x ^{4} - 2 x ^{2} + 1}{x ^{2}} (4 - \frac{x}{16})^{6}

Expand

(4 - \frac{x}{16})^{6} : 4096 - 384 x + 15 x^{2} - \frac{5 x ^{3}}{16} + \frac{15 x ^{4}}{4096} - \frac{3 x ^{5}}{131072} + \frac{x ^{6}}{16777216}

= \frac{x ^{4} - 2 x ^{2} + 1}{x ^{2}} (4096 - 384 x + 15 x^{2} - \frac{5 x ^{3}}{16} + \frac{15 x ^{4}}{4096} - \frac{3 x ^{5}}{131072} + \frac{x ^{6}}{16777216})

Distribute parentheses

= \frac{x ^{4} - 2 x ^{2} + 1}{x ^{2}} \cdot 4096 + \frac{x ^{4} - 2 x ^{2} + 1}{x ^{2}} (- 384 x) + \frac{x ^{4} - 2 x ^{2} + 1}{x ^{2}} \cdot 15 x^{2} + \frac{x ^{4} - 2 x ^{2} + 1}{x ^{2}} (- \frac{5 x ^{3}}{16}) + \frac{x ^{4} - 2 x ^{2} + 1}{x ^{2}} \cdot \frac{15 x ^{4}}{4096} + \frac{x ^{4} - 2 x ^{2} + 1}{x ^{2}} (- \frac{3 x ^{5}}{131072}) + \frac{x ^{4} - 2 x ^{2} + 1}{x ^{2}} \cdot \frac{x ^{6}}{16777216}

Simplify
