解答

展开

\frac{4 ( x + h ) + 7}{5 ( x + h ) - 6}

\frac{4 x + 4 h + 7}{5 x + 5 h - 6}

求解步骤

\frac{4 ( x + h ) + 7}{5 ( x + h ) - 6}

乘开

5 (x + h) - 6 : 5 x + 5 h - 6

= \frac{4 ( x + h ) + 7}{5 x + 5 h - 6}

乘开

4 (x + h) + 7 : 4 x + 4 h + 7

= \frac{4 x + 4 h + 7}{5 x + 5 h - 6}

e x p an d 6 (x + δ x)^{3}

e x p an d \frac{12 x ( 1 - x )}{e ^{2 x}}

e x p an d \frac{v - 1}{6 ( v + 7 )}

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

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