\frac{x + 6}{( x - 6 ) ^{2}}

\frac{x + 6}{x ^{2} - 12 x + 36}

求解步骤

\frac{x + 6}{( x - 6 ) ^{2}}

(x - 6)^{2} = x^{2} - 12 x + 36

= \frac{x + 6}{x ^{2} - 12 x + 36}

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

e x p an d (e^{x} - 17 x)^{2} - 9

e x p an d x y (1 + y^{2}) d x - (1 + x^{2}) d y

e x p an d 2 \cdot (4 + e)

e x p an d \frac{( 2 - x )}{( x + 1 ) ( x + 7 )}
