化简 (x+1/2)x

解答

化简

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

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

求解步骤

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

化简

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

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

使用分式法则:

a \cdot \frac{b}{c} = \frac{a \cdot b}{c}

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

\frac{d ^{2}}{d x ^{2}} ((y (x, C)) (C e^{- x} + C e^{2 x}))

e x p an d \frac{( - 1 ) ^{n} n !}{6 ^{n} ( n + 2 )}

e x p an d \frac{( - a ( n ) ^{3} + a ( n ) \cdot ( 1 + 6 n ) )}{6}

e x p an d 12 (\frac{x - 4}{4} + \frac{x}{3} = \frac{6}{1})
