求解步骤

- \frac{40 ( - 34 x ^{4} - 343 x ^{2} - 208 )}{( x ^{2} - 16 ) ^{11}}

(x^{2} - 16)^{11} = x^{22} - 176 x^{20} + 14080 x^{18} - 675840 x^{16} + 21626880 x^{14} - 484442112 x^{12} + 7751073792 x^{10} - 88583700480 x^{8} + 1 6^{8} \cdot 165 x^{6} - 1 6^{9} \cdot 55 x^{4} + 1 6^{10} \cdot 11 x^{2} - 1 6^{11}

= - \frac{40 ( - 34 x ^{4} - 343 x ^{2} - 208 )}{x ^{22} - 176 x ^{20} + 14080 x ^{18} - 675840 x ^{16} + 21626880 x ^{14} - 484442112 x ^{12} + 7751073792 x ^{10} - 88583700480 x ^{8} + 1 6 ^{8} \cdot 165 x ^{6} - 1 6 ^{9} \cdot 55 x ^{4} + 1 6 ^{10} \cdot 11 x ^{2} - 1 6 ^{11}}

乘开

40 (- 34 x^{4} - 343 x^{2} - 208) : - 1360 x^{4} - 13720 x^{2} - 8320
