\frac{17 x + 3}{( 4 x + 1 ) ( x - 1 )}

\frac{17 x + 3}{4 x ^{2} - 3 x - 1}

求解步骤

\frac{17 x + 3}{( 4 x + 1 ) ( x - 1 )}

乘开

(4 x + 1) (x - 1) : 4 x^{2} - 3 x - 1

= \frac{17 x + 3}{4 x ^{2} - 3 x - 1}

e x p an d π (12 ln (7) + \frac{36}{7})

e x p an d 4 π (5 - 5)

e x p an d y (4 x + y = 11)

e x p an d d x (x^{2} e^{x^{3}} + y^{2})

e x p an d 6 (10 x - 14 y = - 4)
