\frac{k x + g}{( x - h ) ^{2}}

\frac{k x + g}{x ^{2} - 2 h x + h ^{2}}

求解步骤

\frac{k x + g}{( x - h ) ^{2}}

(x - h)^{2} = x^{2} - 2 h x + h^{2}

= \frac{k x + g}{x ^{2} - 2 h x + h ^{2}}

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

e x p an d \frac{5 s + 13}{s ( s ^{2} + 4 s + 13 )}

e x p an d \frac{( x y - x ) x}{y ( y x - y )}

e x p an d (9 ab c^{3}) (14 b c^{2})

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