\frac{x ^{2} - 52 x + 33}{( 1 - x ) ( 2 x - 1 ) ( x - 5 )}

\frac{x ^{2} - 52 x + 33}{- 2 x ^{3} + 13 x ^{2} - 16 x + 5}

求解步骤

\frac{x ^{2} - 52 x + 33}{( 1 - x ) ( 2 x - 1 ) ( x - 5 )}

乘开

(1 - x) (2 x - 1) (x - 5) : - 2 x^{3} + 13 x^{2} - 16 x + 5

= \frac{x ^{2} - 52 x + 33}{- 2 x ^{3} + 13 x ^{2} - 16 x + 5}
