化简 (n+1/2-1) 1/2+0

解答

化简

(n + \frac{1}{2} - 1) \frac{1}{2} + 0

\frac{2 n - 1}{4}

求解步骤

(n + \frac{1}{2} - 1) \frac{1}{2} + 0

化简

(n + \frac{1}{2} - 1) \frac{1}{2} : \frac{n \cdot 2 - 1}{4}

= \frac{n \cdot 2 - 1}{4} + 0

合并

\frac{n \cdot 2 - 1}{4} + 0 : \frac{n \cdot 2 - 1}{4}

= \frac{n \cdot 2 - 1}{4}

= \frac{2 n - 1}{4}

\frac{1}{3} x + \frac{1}{2} = - 3 (\frac{3}{4} x - 5)

(x - 4)^{2} = 17
