\frac{1}{( 7 x ^{2} + 6 x + 1 ) ( s - 3 ) ( s - 1 )}

\frac{1}{7 x ^{2} s ^{2} - 28 x ^{2} s + 21 x ^{2} + 6 x s ^{2} - 24 x s + 18 x + s ^{2} - 4 s + 3}

解答ステップ

\frac{1}{( 7 x ^{2} + 6 x + 1 ) ( s - 3 ) ( s - 1 )}

拡張

(7 x^{2} + 6 x + 1) (s - 3) (s - 1) : 7 x^{2} s^{2} - 28 x^{2} s + 21 x^{2} + 6 x s^{2} - 24 x s + 18 x + s^{2} - 4 s + 3

= \frac{1}{7 x ^{2} s ^{2} - 28 x ^{2} s + 21 x ^{2} + 6 x s ^{2} - 24 x s + 18 x + s ^{2} - 4 s + 3}
