展开 (10x)/((z-1)(z-0.4))

解答

展开

\frac{10 x}{( z - 1 ) ( z - 0.4 )}

\frac{10 x}{z ^{2} - 1.4 z + 0.4}

求解步骤

\frac{10 x}{( z - 1 ) ( z - 0.4 )}

乘开

(z - 1) (z - 0.4) : z^{2} - 1.4 z + 0.4

= \frac{10 x}{z ^{2} - 1.4 z + 0.4}

e x p an d \frac{( x - 4 ) ^{2} ( 125 x - 500 )}{18}

e x p an d \frac{( ( x + 2 ) x ( x - 1 ) )}{30}

e x p an d \frac{a ( - 1 - 2 a ^{2} )}{2}

e x p an d \frac{( 3 ln ( 6 ) - 5 ) ^{2}}{2}

e x p an d \frac{4 x ^{2} - 4 x + 2}{( 2 x - 1 ) ^{2}}
