化简 (x^2)/(sqrt(x-1))

解答

化简

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

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

求解步骤

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

乘以共轭根式

\frac{x - 1}{x - 1}

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

x - 1 x - 1 = x - 1

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

\int - \frac{1300}{x ^{2}} d x

\frac{d}{d x} (\frac{3 x}{x})

t an g e n t f (x) = (2)^{x}, at x = 6

y^{^{''}} + 14 y^{^{'}} + 28 y = 6675 e^{2 t} cos (15 t)
