展开 ((-x+2+(x+1)sqrt(x-2)))/((x+1))

解答

展开

\frac{( - x + 2 + ( x + 1 ) x - 2 )}{( x + 1 )}

\frac{- x + 2 + x x - 2 + x - 2}{x + 1}

求解步骤

\frac{- x + 2 + ( x + 1 ) x - 2}{x + 1}

乘开

- x + 2 + (x + 1) x - 2 : - x + 2 + x x - 2 + x - 2

= \frac{- x + 2 + x x - 2 + x - 2}{x + 1}

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

e x p an d 4 (1 + sin^{2} (3 x))^{3}

e x p an d \frac{( x + 1 ) ^{3}}{x ^{3} - 1}

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

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