expand ((x-3)^3)/((x+3)^4)

expand

\frac{( x - 3 ) ^{3}}{( x + 3 ) ^{4}}

\frac{x ^{3} - 9 x ^{2} + 27 x - 27}{x ^{4} + 12 x ^{3} + 54 x ^{2} + 108 x + 81}

Solution steps

\frac{( x - 3 ) ^{3}}{( x + 3 ) ^{4}}

(x + 3)^{4} = x^{4} + 12 x^{3} + 54 x^{2} + 108 x + 81

= \frac{( x - 3 ) ^{3}}{x ^{4} + 12 x ^{3} + 54 x ^{2} + 108 x + 81}

(x - 3)^{3} = x^{3} - 9 x^{2} + 27 x - 27

= \frac{x ^{3} - 9 x ^{2} + 27 x - 27}{x ^{4} + 12 x ^{3} + 54 x ^{2} + 108 x + 81}

107 \cdot 105

\frac{s + 3}{2 ( s ^{2} + 4 )}

(x^{2} - y^{2} + 2 x y) d x

5.5 j + 8.9 k - 4.7 k - 10.9 j

\frac{k ( 5 k - 1 )}{2}
