\frac{( x ^{2} + 3 )}{( x - 2 ) ^{2}}

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

求解步骤

\frac{x ^{2} + 3}{( x - 2 ) ^{2}}

(x - 2)^{2} = x^{2} - 4 x + 4

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

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

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

e x p an d (3 + 4 t^{4} + 2 e^{- 4 t}) u (t)

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

e x p an d (x - 6) (x +!)
